Abstract: تختلف الاهمية النسبية للمعلومات المرئية المحتواة في الصور. اذ ان البحوث الحديثة في فسلجة الرؤية اثبتت بان الدماغ البشري يتحسس لحواف مكونات الصورة بالدرجة الاولى، اما الانسجة فتاتي بالدرجة الثانية من الاهمية. دفع هذا الامر العديد من الباحثين في حقل المعالج | The importance of visual information contains in images are relatively deferent. Recent researches in psychology of vision have proven that human brain senses the edges of image objects in the first order, where image textures comes in the second order of importance. This problem had motivated researchers in the field of image processing towards finding new efficient methods that work on eliminating less important visual information which gives as a result a brief description containing the most important information. This description serves two domains : the first one is image compression, where it is possible to reduce the amount of data used in representation, which helps in reducing the required transmission time and also needs less storage size. The second one is image denoising, by reducing the importance of noisy data which helps in eliminating the noise, or at least compress its effect.Recently, it has become evident that separable transforms, such as wavelets, are not necessarily best suited for image representation due to their disability of catching line discontinuities that represent the objects edges, which make them unsuitable in giving adequate description for deferent geometrical shapes of these edges. This led to the appearance of the geometrical wavelets which has been proven its superior to nearly all of the classical wavelets in giving higher specific approximations and much more economical in data size of the image. These functions are non - separable and they are divided into two parts : adaptive functions and non - adaptive functions.This dissertation focuses on studying the first and most important function of the family of adaptive geometrical wavelets functions, the one called wedgelets, in addition to propose generalizations to it in order to make it more flexible in catching deferent curved shapes of image edges, which improves its performance in providing much more specific approximations depending on less number of coefficients. This work emphasizes basically in image denoising. And in order to increase the applicable importance of these functions, it has been suggested two methods to estimate the noise level that effects the image, and eventually choosing the best approximation according to this estimation.Finally, a comparison is made between the proposed approximation methods and the classical ones by applying on several tested images that have deferent properties, through the simulation of exposing them with deferent levels of noise. The results of this comparison shows good size of improvement in the performance achieved by the addition of these proposed functions.

The researcher suggested two Bayesian methods for estimation in case of complete data; the first is a loss function obtained by compressing the well known square loss function which called it (The Compressed Bayes Method), and the second is a prior function which is called (The Developed Bayes Method). The comparison between the two proposed methods is done to show the effect of Bayesian estimator, then a comparison done between the best proposed methods with the best well known methods to show which estimator is the more accurate to be used for estimation the scale parameter and reliability function for Rayleigh failure model.The results of these experiments show that White method is the best from the other methods which are used in this research in estimating the scale parameter and reliability function, and the results show that the proposed Compressed Bayes method is better than the Standard Bayes and the Maximum Likelihood methods, while the proposed Developed Bayes method verified that it is better than the Moment method in estimating the scale parameter and the reliability function; and better than the Maximum Likelihood estimation method in estimating the reliability function, and using any of the proposed methods (Compressed Bayes, Developed Bayes) is better than the Standard Bayes method. In case of censored data the simulation experiments proved that the Maximum Likelihood estimation method is better than the Standard Bayes estimation method. A comparison of preference estimation methods is done by using the two standards; Mean Square Error (MSE) and Mean Absolute Percentage Error (MAPE).

Abstract: Some times we faced problem that either the number of treatments used in an experiment more than the number of experimental units inside the particular block or the blocks size large than the number of replicated of treatments, then we have to use incomplete blocks design (I.B.D.); in this design either the treatment appear in block or not; that means the treatment may appear or not in a block, also when the treatments appear in a pair of treatments, this design called balanced incomplete block design (B.I.B.D.). This case makes the B.I.B.D. important by using the randomization to distribute the treatments inside the blocks and create Incidence Matrix, where its elements either zero when the treatment not appears or one when the treatment appears. This kind of design is important in many fields of study especially in the agriculture and in the veterinary medicine …etc. The aims of the previous studies was to find the way for construction of B.I.B.D..Till now the studies keep going to find out the new ways or methods for construction.The aim of this study is to find out a new way for construction. A new way for construction the incident matrix by using steps for building “Genetic Algorithms”, is discussed Genetic Algorithms are theoretically and empirically proven to provide a robust search in a complex spaces.

After that, we can use these results for forecasting to the future taking under consideration : examine to what would happen after changing some of the model parameters, use the standard (depended) methods for testing the accuracy of the identified model which has ability for taking errors in the procedure, and provide balancing condition between model diagnosing and simplicity as well as. This research aims to use some of tests concern with diagnosing of the identified model, and make comparisons among these tests meanwhile. The researcher took some of tests, especially, the modern ones, represented by Dm test which depends on partial autocorrelation function, and which depends on autocorrelation function. We use ARMA models with lower order : [AR (1), MA (1), ARMA (1,1)] that Gaussian distribution. Furthermore, we use the tests concern with linear hypothesis diagnosing for the previous three models, represented by squaring the model errors. We use also, the modified tests in this field. In addition, we use some of nonlinear models, as "Threshold" model, and taking self - exciting threshold autoregressive (SETAR) as a special case. The analysis of time series considered time range under model stationary. Methodology of the research depends on both the theoretical part (Statistical theory usage), and the empirical part (Simulation). The structure of the research has mainly based on four chapters as follow : chapter ONE, consists an introduction, the goal of the research and the historical literature. While chapter TWO, covers the statistical methods that take part describing and modeling the time series, as well as explain the main concepts of time series such as "Stationary". We show also, the "mixed" model with lower order, crossing to examining the diagnosing through some of the standard and modern tests which depends on autocorrelation and partial autocorrelation functions of the standardized residual series that obtained from the original series of the model, by testing the randomization of the model errors and make checking for its convenience and accuracy. Furthermore, we use the modified tests : ( , , )and (Kwan & Sim) test represented by ( , , ) to determine the linear hypothesis diagnosing by compute the standardized residual series squares of the error in the previous three models that mentioned above. We use nonlinear model (SETAR) as well as. Chapter THREE, devoted for the empirical part which contains illustrations to all of what mentioned in chapter two. The researcher has designed some of experiments for purpose of comparing the (standard, modern and modified) tests through computing (P - value) for each model at (0.01) significant level at many simulated parameters, with different sample sizes, and for a number of periods of lags at each sample size, by replicating the experiment (1000) times. Finally, chapter FOUR comprises the conclusions and suggestions that the researcher had recommended

Abstract: تعاني بعض الظواهر من وجود حالة اضطراب في بياناتها بالاضافة الى صعوبة صياغتها وخصوصا مع وجود عدم وضوح في استجابتها، او لكثرة الاختلافات الجوهرية التي تعتري الوحدات التجريبية التي تم اخذ هذه البيانات منها. فعندما تزداد المجاميع لمجتمع ما, لا يمكن اعتبار ذل | Often suffer phenomena and there is disturbances in their data as well as the difficulty of formulation, especially with a lack of clarity in the response, or the large number of essential differences plaguing the experimental units that have been taking this data from them. When growing groups of a population, it can't be regarded as a homogeneous population is increasing because the dispersion between the experimental units in response to that population as well as the error will also be increasingly difficult to build a model of that population.So there was a need to include an estimation method on the classification or underlying discrimination for these pilot units using discrimination or create segments for each item of these pilot units in the hope of controlling their responses and make it more in line style.Has been resorting to the use of the method of a modern and flexible classification is based on the neighborhoods between the views represented by the response variable by classification regression trees : CART. It was the use bayesian approach and the promise of features indicative of regression analysis model classification tree to take advantage of the above information by, and collect trees for explanatory variables are all together and at every stage fork on the other hand, represented the bayesian classification regression trees : BART.In view of the development in the field of computers and taking the principle of the integration of science it has been found that modern algorithms used in the field of Computer Science swarm of birds and other originally illustrated algorithm for the purposes of technology pertaining to distinguish between images or vibrational radio, etc., can be harnessed to serve the knowledge of statistics, which is based Turn on the information production and to achieve success in it. So is the use of genetic algorithm and submit a proposal by modified genetic algorithm, in addition to C4.5 and ID3 algorithms. And without losing the generality has been used as a tool of logistic analysis as important tool.It was a whole performance along with an estimate of the general additive model method of classification of all the methods mentioned in the above. Fitted model as modern and flexible overcomes curse of dimensionality that may occur most modern phenomena of the times when their data analysis.It was the use of simulated samples of different sizes (200, 400, 600) with (1000) replicates. The application was performed on patients with diabetes data for those aged (15) years and below are taken from the sample size (200) was withdrawn from the children hospital/ Al - Eskan/ Baghdad.As proof of the goodness of classification has been using the misclassification error, and as proof of the goodness of estimation has been using the root mean squares error.Was reached important conclusions through a process of differentiation among the six methods above, the superiority of the Classification and Regression Trees Algorithm (CART) is the best in terms of the results that has been reached in empirical side, when proposed Genetic Algorithm is the best in terms of the results that has been reached in applied side.

Abstract: ان الاهتمام الواسع والمتزايد بدراسة موضوع المعولية باعتباره علما يتعامل مع اعمار المعدات ولاسيما احتمالات البقاء ومتوسط الحياة وهذا يعود بالاساس الى التطور التكنولوجي السريع واستخدام الانظمة الالكترونية المعقدة في مختلف المجالات. وعلى هذا الاساس فان در | The wide increasing concern of studying the topic of reliability as a science dealing with equipment ages, especially the survival and life average probabilities rendered to the fast technological development and the utility of complicated electronic systems in various fields. On that basis, the studying the topic of reliability and the connection between the theoretical and applied sides together have a great importance because they are considered the indicator towards stating the extent of efficiency and capacity of the machine and the work system without damages for a long period of time, accordingly, the study of (Weibull Distribution) is a sample of failure functions because this distribution is suitable when failure rates are high relatively at the operating start, then these rates decrease gradually with time increase. Accordingly, the thesis includes mainly a display of a new sample of joint distributions which is known as (Bi - Weibull). This kind of distribution gives more elasticity and more accurate results.Hence, the basic statistical measures and the parameter estimation of (4 - Parameter Bi - Weibull Distribution) were found through (MLE) by using the simulation method (Inverse Formula). In order to reach the research aim, the research is divided into five chapters. Chapter one deals with the topic general backgrounds and function definition including the reliability function. Whereas chapter two is dedicated to expose the methods of estimating the parameters of the (2 - Parameter Weibull Distribution) with displaying the basic statistical measures of (2 and 3 - Parameter Weibull Distributions). As to chapter three, it includes the theoretical side of (Bi - Weibull Distribution) with the exposure of the following three states of this distribution : - (4 - Parameter Bi - Weibull Distribution) - (5 - Parameter Bi - Weibull Distribution) - (6 - Parameter Bi - Weibull Distribution) with their basic statistical measures.Chapter four manifests the research programs and simulation results as well as result analysis. Chapter five includes the conclusions and recommendations the researcher has arrived at

The spatial econometrics is used in following up the spatial effects like the spatial dependence of observations in different points of place, and spatial heterogeneity arising from relations or parameters model that change with sample data in each time we move within the place , those two points have been neglected in traditional econometrics because of their sinconsistency of statistical assumptions and when taking those spatial effects into consideration ,the statistical influence will be of high efficiency. On the contrary, ignoring these effects will lead to loss the information and will not be as efficient as the dependant sample.Because of the difficulty of deriving the posterior function (on which the Bayesian inference depends) up on applying the Bayesian methods especially in cases that the number of probable models is very large as computing the posterior functions for all these samples requires integration for large dimensions functions which is very difficult Mathematically or inapplicable that requires proper methods can deal with such cases like Gibbs and Metropolis - Hastings sampling by analyzing the posterior distribution to number of conditional distributions for each parameter in the model and then the simplicity of inference for each parameter in the model.The matrix of spatial weights is built by registering the contiguity relations for each location with others in a matrix row (w?) and given (1) if there is a relation between two locations (wij=1) and zero, if it doesn’t (wij=0)as i and j refer to the rows and columns in sequence. For making the summation of each row in the matrix w? equal to 1 , the elements of matrix will be calculated according to the proportion : wij/ ?wij and i=1,2…,n j=1 Consequently, we will get the adjusted matrix W.The practical side was focused on the counting of spatial autoregressive model parameters, and these parameters is the vector ? and it is an ordinary regression parameters vector, and error variance parameter (?2) , and the most important of them is a countig of the parameter (?) which is represent spatial dependance parameter.In order to show the role of the spatial, the practical side included taking the real population for childrens between(1 - 19) year, that had iron deficiency anemia (due to from iron deficiency) that admitted to children’s hospitals in Kurkh district of Baghdad (which had been divided into five geographic regions) for 2010. We have suggested that computing the elements in the adjusted matrix to be on basis of the actual length proportion of the joint borders among different locations that lead to get the accurate estimated value of spatial dependence parameter، where value result of spatial dependence parameter (?) was (0.43) when use Metropolis - Hastings sampling method while value of this parameter when use spatial outoregressive function and by using the adjusted matrix was( 0.57) and value of this parameter when use the same regression function but by using the suggested matrix was (0.85).

This research uses the method of Multiple Linear Regression Analysis to find out the climatic elements effecting the productivity of two types of dates (Helawi and Zehdi). The independent variables (climatic side) were the average of the yearly rates for (Maximum temperatures, Sunshine duration, Relative humidity, Wind speed and Suspended dust) in Basra city for the period (2005 - 2014), and the dependent variable was the average of the palm tree productivity measured in (kg), which represents the (agricultural side). The results showed that there are three factors (variables) affecting dates production of (Helawi), which are (sunshine duration, suspended dust and wind speed) because they were statistically significant. As for the (Zehdi), there were two statistically significant variables, which are (Sunshine and Maximum temperatures). The conclusions and recommendations were founded by using the Stepwise regression in statistical package (SPSS v19)

This phenomenon is the delay occurred in getting university instructor to his next scientific title. And as the determination of the principal components number inside the principal components depends on using many methods, we have compared between three of these methods that are : (BARTLETT, SCREE DIAGRAM, JOLLIFFE). We concluded that JOLLIFFE method was the best one in analyzing the studying phenomenon data among these three methods, we found the most distinguishing factors effecting on the phenomenon was (the number of the lectures the university instructor has, the administrative routine, the entertainment activities, family situation, shortage in academic staff, pages number, the use of the internet and the political attitude). So , we should begin with treating these factors as a first step for motivating university instructor to develop his thinking capabilities.

Abstract: مما لاشك فيه ان التجربة العاملية (التي تهتم في وقت واحد وتجربة واحدة بدراسة عاملين فاكثر ),اذ ان لكل عامل مستويات ,وبتوافيق مستويات العوامل تتشكل المعالجات العاملية , هذه التجربة لها اهمية كبيرة في الجوانب التطبيقية وتتسم بالمزايا : - 1انها تسهم في تقلي | 1. It contributes to reduce the cost, time, efforts, and experimental units as a result of the implementation of a single experiment, rather than two or more experiments.2. Provide us by information of the main effects of factors and the effects of interactions of these factors.3. The possibility to compare all different combinations of two or factors to be studied.4. These experiments provide an opportunity to compare the levels of each factor separately, as if the experiment was devoted to him alone.Therefore, the information that we get from factorial experiments always be more perfect and realistic than those we get from single - factor experiments.The factorial experiments held by adopting equilibrium that is oriented common and natural , it might generated cases of unbalance ( what is allocated of the number of plots for each uneven factorial treatment), which may be done on purpose by the researcher (performing the experiment) or it may be due to lack of materials or resources, which leads to identify groups of processing that will be dealt with, or for other reasons like damage or loss pieces or results of experimental subject to certain processing. Such situations cause them a problem of how to analysis it, so the goal of this message is to research deeper theoretically to contribute in find solutions for the research problem and the vast knowing of the analysis methods of the balanced and unbalanced factorial experiments, with discussing the possibility of propose a method or technique to analysis this case. since been in separate theoretical aspect of this message addressed to several ways in addition to provide a proposed way for analysis. The theoretical beside the practical aspects has been improved (Chapter three) to take an advantage of a realistic data experiments (not analyzed) carried out with the Public Board for Agricultural Research (the party was made contract with) where the experiment has been analyzed (balanced and unbalanced factorials) to study the impact of the rice verities factor and also the distances of planting the rice for many characters of the rice crops, as well as study the impact factor rice varieties and planting dates factor on some of the qualities of the rice crop has implemented in Mashkhab station in the province of Najaf, and we used the methods of the analysis presented in addition to the proposed method. The conclusions have been reached regarding the moral of these factors and their interactions and to the possibilities that are available to use each method of analysis and the proposed method. The conclusions have been reached regarding the significant of these factors and their interactions and to the possibilities that are made available to use all method of methods of analysis and the suggested method was as as follows : 1 - perferred to use method frequencies the expected cell in the case of that the data is unbalanced and semi - proportional.2 - perferred to use method un weighted means in the case of that the data is unbalanced and disproportional.3 - perferred to use method of harmonic mean in the case of that the data is unbalanced and two case proportional and disproportional.4 - prefer to using the suggested method (median method ) in the event that the data is is unbalanced and disproportional.5 - prefer to data analysis unbalanced without trying to estimate missing values.

In view of the importance of markove's chains in explaining, and analyzing many of the phenomenae through succession, our research incentive has therefore came to represent markov chains applications on the DNA and considering the conditional transitional probabilities of these chains elements for its great importance in finding the hereditary genetics from DNA compositions. Markov chains has been implemented for the probable alignment of the first, second, third, fourth, and fifth orders. Three means depending on these alignments have been used. Experimentation on four of DNA chains was carried out for human growth hormone and relied on DNA succession for comparison between the three ways that nominate the chain of the greater probability to represent the gene.In addition, a program was created to code and translate the three models of the ORF for the DNA succession and the chains for the three models which start with the start code and end with the stop code. The program was written by Visual basic language to carry out these operations and to yeild sequence alignment between the human growth hormone gene and other chains.The program implemented DNA chains in which the nucleotide number is less than 3000 bases examplified by the human growth's hormone, mouse and chicken growth hormone.As well, entrotoxins produced by E.coli, salmonella , shigella representing prokaryotes were also included one of the most significant conclusion reached is that markov assessment method of calculated weights by means of Chi Square is the best mean for identifying genes from DNA sequences.

Therefore, this research was selected using the data of the survey of the poverty map and maternal mortality in Iraq carried out during the year 2013 by the Central Statistical Organization and using the SPSS to reach the variables that have a direct impact on the level of the infrastructure of the Iraqi family. The analysis was used to analyze the relationship between the twelve variables to reach the factors that actually affect the level of infrastructure, which included housing, electricity, water, sewage system, basic services. The cluster analysis method was adopted and the data of the twelve variables were converted to the standard formula. To eliminate the difference of units of measurement of these variables and thus ensure the validity of the implementation of the stage related to the process of data classification and determine the extent of the relationship between the Iraqi provinces in terms of similarity or difference and in the last stage to enter the methods of analysis and analysis. Two main methods of analysis were used : the main vehicle method and the main axis method. It was obtained through the results of the main vehicles method that there were two factors (the value of the underlying root is greater or equal to the correct one) namely housing, electricity, water and basic services factor with an explanatory capacity of 85.469 (847.82%) of the total variance, and the remaining 17.153% of the total variance, and the remaining 14.531% Due to other factors. Thus, the cluster analysis used two methods of hierarchical analysis, ie, the single link and the total linkage. The results were close to some minor differences among them. Most of the aggregates' tables were close to a small difference in transactions. This difference depends on the methodology of each method.

Many researches and books have been written about the subject and these researchers are different from one to another depended on the methods followed up. But the estimation with Bayesian methods for these equations , especially when the internal variables (classified binary ) being considered one of the subjects that have not been researched greatly. Thus , the researcher has tried to shed light on some methods of Simultaneous equations in case of binary variable by using the classic method and Bayesian method , along with a suggested way that being applied on the samples of the relationship between blood pressure and psychological pressure. The researcher has used the classic method and considered it as raw information for using the method of Bayesian in estimating the Simultaneous equations system. It has been compared between the classic method and Bayesian method and also methods of Bayesian with the suggested method according to the measurement of ( Mse) for specifying the better method for estimation. Problems have been specified lying in non - functionalizing the former information about the parameters in the process of estimation by using the known traditional methods and that lead to the less efficiency if not using it. Thus , it should resort to other methods as method of tradition , The goal of the study is to know the mutual interaction between the blood pressure and psychological pressure and comparing the traditional and Bayesian method in the estimation of Simultaneous equations of internal variable , classified binary by using many methods for Bayesian estimation with the suggested method for getting to estimations that are more close to values of the real parameters. it has been reached to many results ,most of which is the Bayesian method and suggested method that have been better in estimation than the classic method, besides there are mutual effects between blood pressure and psychological pressure and the most losing functions in estimation which is the " Q losing function"

Then, calculated life tables of mortality data for a particular year the population of the community, so it reflects the rate of death of the community in somehow. There are two types of life tables, called : (Complete Life tables) and were based on the age at death on the basis of single - year age groups (0,1, 2,3,..., 81+) and were usually obtained in a manner comprehensive survey or census in order to provide detailed information on the population. The second type called (Abridged life tables) were assumed from equal death rate for ages converged with each other and are therefore based on the age at death on the five - year age groups (0 - 1, 1 - 5, 5 - 10, 10 - 15,..., 80+) which is different from its predecessor and less accuracy than is obtained in a manner sample survey. In the absence of census of our beloved Iraq, where the last census was in (1997), so be getting the calculated probability of survival through accurate (survival function) within the life tables for single - year age groups was extremely difficult and mired with disorder problems you need to mathematical treatment in accordance with the distribution of probabilistic statistical but it's distributed data showed the distribution of the Generalized Gamma : (GG) with three parameters as the best fit of the data, with this distribution in turn includes the integration of (incomplete gamma function) is implicitly making it more difficult traditional appreciation. So two major goals were arise in this thesis.The first goal of a practical application goal, using (Sprague multipliers) to convert a five - year age groups into single age. The second goal of theory using the method of Principle of Maximizing Entropy : (POME) in assessing the function of survival and to deal and overcome the turmoil and volatility demographic data collected from (Iraq Household Socio - Economic Survey : IHSES II 2012). This thesis had studied the function estimating survival data mentioned above on two parts : the first part, parametric estimation methods which is the method of Principle of Maximizing Entropy : POME, the Classical method is the Maximum Likelihood : ML. The second part, has included nonparametric method to estimate survival function by nonparametric method (Kernel Smoothing) been used as (Gaussian function). The estimation methods were compared using statistical criteria are the root mean squares error (RMSE), and the average absolute percentage error (MAPE). Among the most important conclusions, was the preference for a ML method and kernel method when a simulation to get the proportions views of the probability distribution (GG) and in a manner Inverse Transformation Method : ITM only single - year age groups sized by (n = 81) and repeat the experiment (300) replicates. As well as to reach that way entropy is the best method dealt with five - year age groups, where in the case of single - year age groups, the nonparametric kernel was best in when the practical application part. Life tables using MORTPAK program as it has been considered survival function results (UN) calculated values real and comparing the methods of the three appreciation. One of the main recommendations, the use of the (POME) to overcome the turmoil of demographic data, especially a five - year age groups and the use of Sprague data conversion from five - year age groups to transactions single - year age groups and the use of nonparametric method of kernel to assess the function of survival of the single - year age groups and entropy for five - year age groups data.

One of these sectors is population studies.The researchers studied the problems of census , and data collection related to population (i.e. Births , deaths and migration) , which is considered of great importance in the field of planning , management and development studies. This study comes as a part of the studies focused on demographic characteristics and concentrated on mortality , which is often faced by the problems of incomplete and incorrect data , mainly the lack of mortality records specially in developing countries. The study focused on mortality data in Iraq during the period 1987 - 1997 , aiming at evaluating and estimating some of the related indices such as (life expectancy at birth , age - specific mortality rates , etc.).The study excluded the region of Kurdstan (Arbil , Dohok and Sulaymania) because this region was not included in 1997 census moreover the difficulties in obtaining registered deaths in this region since 1991. The study compares three methods for estimating infant and child mortality rates (i.e. Brass method , Feeney method for estimating infant mortality and Preston - Palloni method) the study concluded that Brass method is the most relevant for estimating infant and child mortality in the light of the hypotheses of each method and its characteristics and the needed data. By using 1997 census data in Iraq and depending on UN. Model for developing countries (general model) , the study achieved to the adjustment of mortality probability (Logit method). In dealing with mortality for (over 5 years old persons) , three methods were compared for estimating completeness of recorded deaths (i.e. Brass growth balance method , Preston - Coale method and Bennett - Horiuchi method) based on the hypotheses of each method and its characteristics and the needed data. It was found that there was no reason for preferring one method on another , therefore , the three mentioned methods were used depending on registered deaths (collected from Ministry of Health data) for the period 1987 - 1997. The study results showed that Brass growth balance method was not relevant for the studied mortality data in the Iraqi society. therefore , its results were neglected , and the results of mathematical mean of Preston - Coale method and Bennet - Horiuchi method were considered as representative of completeness of recorded deaths. It was found (0.725) for males and (0.845) for females.In order to estimate some mortality indices , bridged life tables were built for the years 1997 and 2002 for males and females in Iraq. The analysis showed the rise of life expectancy at birth about (1.2) years for males and (1.3) years for females during the above mentioned period.Finally , the study discuses its conclusions and recommendations.

Abstract: تعتبر شبكات الاعمال من الادوات المهمة في التخطيط والسيطرة على مراقبة تنفيذ المشاريع باقل كلفة ووقت ممكن اذا ما توفرت الموارد التي تغطي حاجة تلك المشاريع.ونظرا لاهمية موضوع شبكات الاعمال ارتاينا البحث فيه بهدف التوصل الى طريقة لحساب وقت انجاز المشروع الك | Networks are considers as the most important instruments in the planning are controlling probation of projects implementation with minimal cost and time if there are sufficient resources cover the need of these projects.And respect to the importance of the topic regarding networks, we saw the search in it so as to reach method for calculating time of implementation of the total project in Probabilistic PERT networks, which are different from PERT networks because each stage in Probabilistic PERT networks represent random variable which has certain probabilistic distribution. So, time of implementation of the project will be another random variable, while in PERT method the times being already specified for each stage. We shall calculating this time after finding the total probability function for networks of the project.Moreover, we shall perform striking the necessary time to doing PERT network by application Fulkerson method which depends on every possible investigations to perform the project’s stages, which concentrate on that which have the maximum possibility of an event, and so the Fulkerson method being approximation to that which depends upon the probability function, but we shall concentrate in our research on the probability function because it gives additional indicators to the performing time. This will appears as clear through comparing the results that we shall reach after application the two methods. Where this was applied practical in one of our productive enterprises and it is the public enterprise of leather industries.According to above cited, we divided a thesis into four chapters; the first, takes the introduction and the objective of the probabilistic PERT networks topic as well as topic’s background, while the second chapter takes the theoretical aspect of the topic that encompass displaying method of PERT and an analysis that depend upon beta distribution besides displaying the symbols used in Fulkerson’s method to finding the expected time for implementation of the total project and finding variance of time regarding the total implementation and then estimating the probability function to the project time. The third chapter takes an applied aspect of the topic, so after gathering data, we tested it for conformity goodness of fit and then, we calculated mean and variance of the time regarding project total performing according to PERT and Fulkerson methods, and then we have finding the mean using probability function after estimate it.The most important what we have reached from the conclusions and the recommendations we shall display it in the fourth chapter of the thesis

Causing a problem of not investing the oil spot which fall under mined areas , Geographic information systems was used in spatial analysis of the mines problem in Basra through natural distribution standard.After identifying the areas of mines presence calculated the cost by the government due to the presence of mines and remnants of war inside the oil field ( Sindbad ) and the ninth spot which are located nearby the Iraqi - Iranian border the reason for planting of many minefields by the Iraqi government and the Iranian government was that the wars which took a place in this area , And the study showed that the presence of mines and remnants wars within the oil spots the government must have a financial obligations to clear these areas from mines and make it safe for the extraction of crude oil.Although the study showed that the geographical distribution pattern of mines at the study area ( Basra ) it is close to the pattern of massed because the gathering of dangerous areas at the middle of Basra due to the proliferation of remnants of wars as a result from the air and ground bombardment to vital facilities inside the governorate. From this above we conclude not to leave and neglect any oil spot containing mines and wars remnants and conducting surveys and removals for the purpose of clearing them from the wars remnants and make it safe for the purpose of investment to benefit from oil imports , especially that the world oil price will decline over time , And to provide full protection of oil fields and wells from terrorist and military operations In spite of they are frequently locked to sabotage as arson operations by ISIS

Abstract: اكتسبت نماذج البيانات المزدوجة اهتماما بالغا وخاصة في الدراسات الاقتصادية والطبية والمالية لانها تاخذ في الاعتبار اثر التغير في الزمن وكذلك اثر التغير في المشاهدات المقطعية على حد سواء في بيانات عينة الدراسة، فضلا عن وصف البيانات من خلال تقدير الانموذج ا | Panel data models have gained a great importance especially in economic, medical, epidemic and financial studies. Because these models take into consideration the impact of the change in time, the impact of the change in sectional views alike inherent in data of a study sample, in addition to describing data through Estimation of the appropriate model. In this thesis, we address the use of method of nonparametric regression in diagnosing and Estimation a model of panel data , as there are specific assumptions related to vector of random errors are not verified. This is because we are going to talk about a nonparametric problem and existence of Heteroscedasiticity and Auto correlated errors which make the process of Estimation wrong, or sometimes not possible. A model has been diagnosed through disclosing all of the problem of Heteroscedasiticity through the use of test (1996) (Zheng) and the problem of Auto correlation by suing test (2013) (Su and Lu). It has been indicated through handling a Nonparametric Hausman Test that the final model adequate for research data is Nonparametric Panel Data Model with Random Effects. Thus, finding Nonparametric Estimator has been tackled through dealing with each problem individually alongside with addressing methods of choosing the smoothing Bandwidth of the model of Random Effects. In case of correlated errors for all techniques of Nonparametric Regression, there are methods to deal with this problem, however all of the said depends critically on addressing estimation methods reliant on finding the choice of an optimal smoothing Bandwidth using more accurate standard until the removal of error process to attain an edited smoothing Bandwidth , of any correlation, is achieved. Then, we could Estimation a model by using Estimation methods. In case of Heteroscedastisity, treatment could be achieved through determining weight by Kernel Estimator, then to be used for the exclusion of the effects of Heteroscedasticity in the study variables through using estimation methods and provision of proposals for classic Nonparametric methods. The formulation of simulated experiments of used models and verification of performance of traditional and proposed methods, for all sample sizes and three levels of standard deviation trough the use of (RAMSE) standard, have been carried out in this thesis. One of the most significant objectives of this study is the selection of the best Estimation method produced by simulation through applying it on a group of balanced Panel Data (longitudinal). This could be conducted through carrying out a practical application to state the effect of the role of gross domestic product on fixed market prices measured in a US Dollar (x) in the state budget measured in millions US Dollars (y) for the period (2003 - 2015). This could be approached through depending on genuine data related to general budget for the Arab States measured by millions US Dollars. The gross domestic product has been focused on since it is the most important economic variable that impacts the budget, as an explanatory variable according to the viewpoint of the competent people for the period (2003 - 2015). The main conclusion in the experimental side is a clear preference in absolute terms to the fortified proposal of Least Square Support Vector Machine for Regression by using an (MGCV) standard on other used Estimation methods. This is in case existence of Auto Correlation as well as provision of a verified proposal for Propose (LCNE), relying on a Span, a selection standard, on other used Estimation methods in case existence of Hetroscedasticity, of all sample sizes, all cases and three levels of three standard deviation. As to practical side, an appropriate model has been diagnosed. Also, compatibility of the best method has been proven in the experimental side alongside with practical one, and the most appropriate for a model by using (RAMSE) standard

The levels of one factor normally distribute randomly over the strips of the queues and the levels of the other factor, and also randomly over the strips of the colons. By changing the randomization category (put the restrictions on the way of randomization) many kinds of designing the Strip - Plot appears. Hence, the aim of this research came to put the spot on these categories and put their mathematics sample, the statistical analyzing of each category, their usage’s, their characteristics, their features and their standard mistakes and to test the differences between the treatments average by using the method of Least Significant Differences. We cleared how to treat the problem of the one replication (because of loosing the mistakes) to test hypotheses by two methods. Finally we applying the kinds of the strip - plot designs practically standing on an experiment diagrams done in Abo Guraib Station yield that belong to Eebaa Center For Agricultural Researches. The program was written in ( Visual Basic ) language to make the statistic analysis for these experiments and applying practically the treatment of the repetition one.

Abstract: لقد شهدت طرائق الانحدار اللامعلمي اهتماما ملحوظا في السنوات الاخيرة كان السبب في ذلك هو ان التفكير المعلمي الصرف المستخدم في تقدير منحنى الانحدار لا يتوافق مع المرونة في تحليل البيانات.ومع التطور المنجز في اجهزة الحواسيب من الناحية المادية وكذلك انجاز | In recent years, too many considerations have been given for the Nonparametric Regression methods. This is for the reason that the concept of pure parametric; used for the estimation of Regression curve, does not cope well with the flexibility needed for data analysis.With the progress made in computer machines, in terms of economy and running performance, it has become possible to develop many of Nonparametric Regression methods theoretically. Though many of these are still under perfection, and facing a number of problems.Hence we see the importance of focusing on methods related to smoothing of Nonparametric Regression functions. This is for the purpose of producing the best methods convenient for various models. And for the Distribution Random error, in its two cases; Normal and Contaminated. Thus, the most important purpose of the research, is to find what the studies so far, have offered in the field of Nonparametric Regression. Also to find alternative or modified methods; which are reliable for the treatment of conditions of failure regarding the methods in use, as well as to alleviate the complexity of some methods, especially those related to Bayesian procedures.One of the most outstanding aims of the research focuses on the study of Nonparametric Regression using Bayesian variable selection. This suggests a modified technique to be reliable and of less complexity than the original one.Amongst the other research intentions, when data are contaminated with outliers, is to explore the Robust Nonparametric Regression, using Bayesian variable selection method. Also to suggest a modified Bayesian method; resistant to outliers, and of less complexity than before transformation. As well as offering suggested methods for Robust Nonparametric Regression. This is of the feature of having less sensitivity towards outliers and reliable in comparison to very few techniques supplied with robustness, as the Bayesian approach.A simulation model has been performed with different distributions, for the random error and for a number of models.To verify the performance of such methods, many criteria have been carried out.To satisfy the purpose of this research, the study has been divided into five chapters. Chapter I consists of an introduction, the problem under research, its importance and purposes. It also covers a literature survey. Chapter II covers methods for smoothing Nonparametric Regression. While chapter III is devoted for Nonparametric Regression and Robust Nonparametric Regression using Bayesian variable selection method. Also in this chapter are details of the suggested methods. Then chapter IV implements the experimental part of the study. Finally chapter V comprises the conclusions and suggestions that the research has recommended. As well as the future studies, which have been proposed regarding this research.

These theories deal with the study of ages to investigate and study the behavior failure time at posterior time. Reliability theory is one of those standards that show the performances of any unite for an expected period of time. It is also considered an indicator for future planning.Accordingly, reliability theory is adopted to study and analyze behavior of failures and the factors behind such failures. To achieve this, the parameter estimators of failure models, with good prosperities and efficiency, are required to count the reliability estimation. Therefore, it is of keen significance to study the methods and techniques for getting the parameter estimators of failure including the parameter estimations of a mixture failure model. These estimations have a great role in reproducing complex cases of non - homogeneous populations. Like the importance of the normal distribution for biological studies, the exponential model is considered of a great significance for the study of failure models.The study aims to estimate the reliability function by employing various methods to estimate the model parameter exponential mixture. To achieve this objective, this study is divided into four chapters. Chapter I shows the introduction and the literature review. Chapter II defines some key concepts of the topic; it also presents the theoretical framework for the employed methods of estimation for a number of parameter estimator method’s complete sample of a mixture of two exponential distributions with different two parameter and percentage p. them of normal school such as Maximum likelihood method estimator and symbolizes her short (ML) and the method of moments and symbolized short (MO) and the least squares method and symbolizes her short(LS) and the least squares weighted and symbolized short (WL) and propose application Bayesian Method using (Lindley' s approximation) of this mixture distribution as not used in Iraq (by informed researcher) and study the behavior of a function failure rate for this distribution using expression w(t) which is also taught for the first time in Iraq, according to the informed researcher. Chapter III is divided into two sections. The first section includes the application of imitation style for generating data and performing a sample application based on the theoretical background. The second section reports about a field work on one of the public institutions for electrical industry. Chapter IV shows the results and conclusion of this study.

It has been used several methods parametric to analysis these types of designs. which are difficult to analyze in sometimes because of the not provide conditions analysis of variance for repeated measurements experiments. The second objective of the message is application this kind of experience in the medical sector by studying a particular phenomenon characterized by a repeated measurements represented Thalassemia in Wasit province. Where he was studying three types of experiments the existence of a repeated measurements It is experiments with a one factor and have a repeated measurements on the same element, Factorial Experiment qxp repeated measurements on one factor, and Nested - Factorial experiment repeated measurements on one factor. As well as the use of methods of transfer to ranks (Rank Transformation) as one of the solutions that have made conditions analysis of variance to experiments measurements repeated of (distribution Normal random and independent for experimental error, homogeneity of variances, the lack of correlation between the averages and variances, spherical). Satisfactory because the transfer to ranks makes the data on the most homogeneous and normal, although we have identified a condition analysis of variance exclusively for the purpose of comparison by the value of the P - Value. The data can be described about Thalassemia in Wasit as follows : were assessed Standards quantities of iron (Fe) in the letter, groups this data classified into two groups, the first group included 20 patients (10 males, 10 females) and who have been subjected to the first chemotherapy (axja) by mouth for four treatment cycles (treatments) of each period lasts 30 days , and the second group included 20 patients (10 males, 10 females) who were exposed to second chemotherapy (Desferal) by injection into the skin or muscle of four treatment cycles (treatments), where each treatment cycle lasts 30 days. the most important conclusions that have been reached is that the Data Transformation by ranks led to the provision of analysis of variance conditions for experiments repeated measurements distribution the normal errors and homogeneity of variances and correlation between mean and variance, as well as a spherical condition. Through the four applications we believe that giving the first dose of the drug to patients has led to high amounts of iron to patients over time and this type of treatment is used when high amounts of iron ratio. As well as when you give the second dose of the drug to patients has led to high amounts of iron to patients over time, but at rates lower than the first treatment and this type of treatment is used when a weak proportion of iron in the blood of the patient.

This thesis deals with multicollinearity problem by using some of generalized ridge regression methods (GRR, MJR, GJR, GL, AUGRR, and AUGL) as well as our proposed method (Almost unbiased Generalized Jackknife Ridge) (AUGJR). In addition, these methods are compared with parameter (k) in ridge and parameter (Liu D). These methods are evaluated based on the mean squared error (MSE) to obtain the best method of these methods with the suitable parameter.To evaluate these methods, we use simulation studies by using the R statistical program. Five variables are simulated with different sample sizes (n=15,20,60,300), different variances (0.16,0.13,0.18) and different correlation coefficients (r=0.16,0.13 and 0.18) with (s=10 and 2). The results show that AUGL, AUGJR and AUGRR are the best methods in terms of the MSE. The differences are very small among them. The methods are also evaluated based on real data example (Rail transport for the passengers and cargo), which is obtained from Iraqi Ministry of Planning.We first detected the problem of multicollinearity by using the Variance Inflation Factor (VIF) and Condition Index (CI). Then, we build a model of revenue for transportation after they have been estimating its features at the best methods.

Abstract: مما لاشك فيه ان لكل اسلوب من اساليب المعاينة مزايا ومبررات في استخدامه، وغالبا ماترتبط عملية اختيار اسلوب المعاينة بجانبين اساسيين، اولهما معيار التجانس بين المفردات سواء على المستوى الكلي ام على مستوى اجزاء(او مجاميع) من المجتمع، وثانيهما الامكانات المتا | There is no doubt that each technique of sampling techniques has advantages and reason for using it, and mostly the correlation of choosing sampling technique with a essential two sides, first of them is the standard of homogenous between units as for all population, and the second one is the abilities that are available to fulfills survey. And in using Stratified Random Sampling Technique in evaluating the suitable population to apply an important role to get a high efficiency estimator to compare with other Sampling design. As the target of this searching is to get the best ways that increase the accurate estimation of the Date Palms number in Basrah governorate and in using different kind of sampling estimator, the comparison has been done between the mean variance of Simple Random Sampling and the mean variance of the Stratified Random Sampling, and it is clear in the comparative results hat using Stratified Random Sampling give the best estimation. The determination of strata boundaries (strata formation) have interested role in obtaining efficient estimators, several strategies of strata formation were constructed, it is proved that the approximated frequency strategy at ?= ½ is the most efficient, researchers discussed developing this strategy through using different values of (?), or different sample allocations. In this searching three approximately frequency had been applied , and to divide the population into strata and point out the optimum limit strata, and the sample allocation has been determined by using Neyman distribution. And it is clear in the result that using the approximated frequency is the nearest and efficient to estimate the Date Palms number in Basrah governorate, by counting the Stratification mean variance and the stratification mean for the three approximated frequency. And the reason to know wither the Stratified Random Sampling is efficient and better than the Simple Random Sampling in evaluating the Date Palms number the experiment of the hypothesis between two population has been used, the results of that experiment show the difference between the two means that lead to reject the Null hypothesis and to accept the Alternative hypothesis, according to this the search recommended to use the Stratified Random Sampling according to the new divided stratification by using frequency, taking into consideration using Neyman distribution o determine sample size and sample allocation

Abstract: ان الدراسات والبحوث التي تخص الفقر متعدد الابعاد لم تجد اهتماما الا في السنوات القليلة الماضية ولاسيما بعد ان اطلقت مبادرة اكسفورد التابعة لبرنامج الامم المتحده الانمائي تقرير التنمية البشرية لعام 2010، حينها اصبح الاتجاة بالتحول من نمط القياس الفردي الى | Studies and researches that concerned in multidimensional poverty did not find any attention, except for the last few years especially after the initiative of oxford - the report of human development of 2010, since then, the pattern changed from the single measurement to multi measurement, by describing poverty in many variables instead of one variable (income). According to the initiative of oxford - the report of human development, Multidimensional poverty on a national scale in Iraq contain five main dimensions dimension consists several indicators (education, basic services, level of living, feeding and health and employment), each dimension consists several indicators. This study came to measure multidimensional poverty and knowing the poor rate and the poverty severity, on a national scale in Iraq and its(18) governorates, and also on an Environmental Scale (rural, urban), and then using the analysis of multidimensional poverty (Principal component Method), to determine the variables causing in forming these elements which affect multidimensional poverty, on the other side, and the central statistical organization also can benefit from this study, because this method has been used in Iraq recently. The main conclusions of the research was that the multidimensional poverty has recorded differences in Poverty rates between the governorates, since that (Erbil) has recorded the lowest Poverty rate than other governorates, and when compared with (Wasit) which has recorded the highest Poverty rate, it will show that on each poor individual in (Erbil), on the other hand there is Five poor individuals in (Wasit), also the severity of poverty was high in all of the Governorates, even in governorates that has low poverty rates. On the Environmental scale (rural, urban), the multidimensional poverty in rural was four times bigger than urban. The results also shown that There are five main elements that affects multidimensional poverty on an Iraq scale, in another side, there were six elements effecting in (rural, urban) scale.

And featuring this type of data link between the presences of her observations. And possible expression of clustering in terms of the relationship between measurements on units within the same group, the statistical models makes it imperative for the link account at every level, because failure to do so leads to misleading results. Hence the importance inside the Observations link to the estimating of the function non parametric for cluster data where the use of parametric method for ICON is always desirable to estimate some functions Because of the shape of the data is unknown in advance the appropriate function or as a result of the existence of some obstacles so it is the use non parametric method to estimate (smoothing) Nonparametric function.. Research has shown developed in recent times on the use of non parametric regression when parametric the assumptions are unfulfilled. And non parametric regression allows greater flexibility of functions dependent variables resulting from the data. Previous research has touched on the case of cluster data estimating the ways non parametric and semi parametric methods and was adopted state of neglect of the link within the same cluster property data that distinguish cluster data is particularly. And local kernel estimator achieved more efficient negligently correlation within clusters (even if the correlation is in the interest the study). While some touched on the case taking correlation between Observations per cluster using the estimated equations. Others had created the kernel methods in the case of cluster data behave completely different from the behavior of the capabilities of the spline estimator as has achieved kernel methods results more efficient when the neglect of the link within the clusters, while spline methods results achieved less variance of smoothing fixed parameters at taking the link inside clusters into account in the estimation process.So in this thesis will be nonparametric function estimating for clustered data using the Seemingly Unrelated Kernel Estimators, and The Generalized Least Squares Smoothing Spline Estimators and propose Robust methods and comparison of the methods listed above to indicate the best estimate of the nonparametric function estimating for clustered data, taking into account the structure of the link within the clusters were cluster data, The adoption of cluster data, which has the same number of explanatory variables within each cluster. To achieve this, thesis was divided into five chapters, the first chapter included introduction and aim of the research and reference review, either Chapter II now include the theoretical side which discussed the methods used to calculate the non parametric function of cluster data in the presence of the link. While included Chapter III experimental side (simulation) and the application addressed method in the second chapter and the statement of the best way has less (MAE) or (MSE). and either the fourth chapter includes the applied side to the real data for the proportion of white blood cells and its impact on the proportion of blood per patient (cluster) and Chapter V which includes the most important conclusions and the recommendations.it is through simulation experiments have been finding the best way to estimate the non parametric function for cluster data and a way The robust Generalized Least Squares Smoothing Spline Estimators in the case of a correlation. It was the application of all methods of the practical side using real data about the proportion of white blood cells and their impact on the proportion of blood hemoglobin for patients with blood cancer (leukemia).

Abstract: This research work is a study of multivariate analysis of variance model (MANOVA) for the design of split - split plot to a complete randomized block. As it is an important method for determining whether the response variables are influenced with each other or in other words whether the correlation between the variables of a force such that it influence the decision taken concerning the applied hypothesis. When we don’t ignore the relationships which are created between the responses variables lead us to generalize the tests in the univariate analyses about the means of normal population to be changed to tests involving mean vectors responses taken from multivariate normal population. Ignoring the existing relationships between variables lead us to untrue conclusions, so in doing the (MANOVA) gives us a full picture of the experimental factors and their interaction in the experiment as a whole. The concentration on doing the (MANOVA) should not be at the expense of the study of the univariate analysis. So the research work involves the problem of heterogeneous in sub - sub plot variances, which is considered one of the important problems put forward by other researchers which may limit his work in special procedure. We are interested in solving this problem by using a univariate analysis procedure after splitting the error of sub - sub plot and then finding the standard deviation used in comparison testing between about the third factor (c). Then comparing them with the standard deviation used, if we assume the existence of homogeneity in variances of sub - sub plot.

Abstract: The primary purpose of our thesis is to assess the importance of using empirical Bayes approach in regression analysis. At the first some empirical Bayes techniques in point estimation are considered. It is well known that in point estimation with a squared error loss function the Bayes estimator is the posterior mean. In the empirical Bayes approach we must construct a consistent sequence of estimators for this posterior mean using past experience. This construction is done for three general families of distributions. New estimators for the parameters in the simple orthogonal linear regression model are presented using not only the usual random sample of observations but also past experience in the form of previous estimators of parameters in similar but independent situations. The regression parameters are considered to be random variables. Bayes estimators are given for a squared error loss function. Even though the prior density of the parameter is unknown the Bayes estimator can be written in terms of the marginal density of sufficient statistic. This marginal density can be estimated empirically , thus forming the empirical Bayes estimator. Empirical Bayes estimators for the parameters in the general linear regression model are presented. These estimators by pass exact knowledge of the prior distribution of parameters by means of supplementary informations from similar independent experiments. The case in which the error variance is unknown and may vary from one experiment to the next is included. Some basic concepts in shrinkage estimators are introduced. The definition of multicolinearity as the existence of near linear relationships among the independent variables is given. Effects of multicolinearity on estimated regression coefficients are explained. Sources of multicolinearity and methods of detecting multicolinerity are presented. The method of ridge regression is given as one of several methods that have been proposed to remedy multicolinearity problems by modifying the method of least squares to allow biased estimators of the regression coefficients. The technique of ridge regression first proposed by Hoerl and Kennard has become a popular tool for data analysts faced with a high degree of multicolinearity in their data. Ridge solution properties and methods for choosing the ridge parameter are presented. The first method is graphical applied by using graphical display called 'ridge trace' the second method is the iterative method proposed by Hoerl and Kennard. The equivalence of ridge regression estimator with Bayers estimator is proved. Bayesian methods are employed for choosing the ridge parameter. An empirical Bayes estimator of the ridge parameter is presented. An empirical Bayes estimator of the ridge parameter which result in minimax ridge regression estimator under strawderman's loss function (formula 2.81) is also presented. By minimax estimator we mean an estimator which is uniformly better than the least square estimator in terms of risk. In the practical part of the thesis we apply ridge regression analysis to the set of actual data suffer from multicolinearity. Three methods are employed to determine the value of the ridge parameter. Comparisons between the three methods are made on the basis of various statistics that might go into the choice of the ridge parameter. According to these comparisons we conclude that the value of the ridge parameter obtained by using empirical Bayes approach (formula 2.78) is better than the other two methods. Ridge analysis is repeated for another set of experimental data obtained by constraint simulation. The same conclusion is obtained when the dependent variable is any one of the variables Y2 ,..... Y6.

The main reason of that was the researchers’ belief that pure parametric methods for estimating the regression curve have shortage with the flexibility needed for data analysis - especially the quantitative data - . With the progress made in computers, in both hardware and software, it has become possible to develop many of Nonparametric Regression Methods including the "Quantile Methods". In spite of that, the researcher see the most of papers and articles concern univariate case, where the researchers about bivariate case still with limited. In the other hand, the researches extension to multivariate case nonexistent in Iraq - in the scope of researcher’s knowledge - , which gives an extremely importance for the aim of this study, to bring attention for alternative methods or modified methods that can be efficient ones to improve the currently methods. Thus, the most important purpose of the research, is the use of Tow - Stages method, which helps the researchers to compute Nonparametric estimators for the components of Nonparametric models to avoid the curse of dimensionality.It divideds the components to set of points called "Quantiles" , then estimates the quantile function by one of the quantile methods we explained in this research, ( Marginal Integration, Backfitting, and Tow - Stages ). The simulation has been designed for the illustrated models and it has been checked about the estimation methods performance by using the Absolute Deviation Error (ADE) criterion, then compute the Average Absolute Deviation Error (AADE). From noticing the simulation results, it was shown that the best estimator was Tow - stages estimator in case of high correlation and / or high dimensions. To achieve the purpose of this research, the study has been divided into five chapters. Chapter one, consists of an introduction, the aim of the thesis under research, and a literature survey. Chapter two covers the parametric regression quantile estimation. While Chapter three devoted for Nonparametric estimations methods. Chapter four devoted for Simulation experiments and practical experiment with real data. Finally, Chapter five comprises the conclusions and suggestions that the research has recommended.

The use of simulation in the style of the experimental side for a comparison between the methods adopted in research using polluting ratios (0% 0.1% 0.10% 0.15% 0.20%) and volumes of samples (500, 1000.1500), In addition to the use of different values of the parameters it is found favorable proposed method (BM.Bayes) be when the values of the two parameters (?1, ?) close to each other when any correlation strength is high , Simulations were also on the values of the parameters of the real series that have been estimated in a manner program application (MLE) and some of them were far from any values that weak correlation strength , It turns out that the best method was the proposed (BM.Bayes.Shrinkag). In the practical side it has been stated in the application of the theoretical side of the building stages of the model and testing of those stages on a series of (1254) Show prices daily sales of Basrah, for the period (2 \ 1 \ 2008 - 31 \ 12 \ 2012) through the application of the proposed third method (the reduced method) (BM.Bayes Shrink) which was best when applied to the estimated values of the parameters in a manner (MLE) in the experimental side as it made less (MSE) and estimate the appropriate model GARCH (1,1) proposed the adoption of the reduced way (BM.Bayes.Shrinkag).

Abstract: من الملاحظ ان معظم البحوث والدراسات في مجال الاحصاء ولاسيما في حقل المعولية تهدف الى الحصول على مقدرات ذات مستوى عال من الكفاءة. لاسيما عندما تكون بيانات العينة قيد الدراسة ملوثة. او في حالة عدم التحديد الدقيق للمعلومات المسبقة او في حالة ظهور الحالتين م | It is noticed that most of the researches and studies in the field of statistics particularly in the field of reliability aiming to obtain estimators of very high standard of competency specially when the sample data under study is contaminated, or in the case of not determining accurately the previous information or in case both cases appear together. From here came the objective of the thesis to come to competent estimators of the approximate reliability of Weibull distribution which is considered one of the common failure models. Through studying the ordinary procedures represented in the maximum likelihood method and method of moments and white’s method as well as the ordinary robust methods represented by the method of M - estimate and bayes procedure as well. Therefore bayes procedure was suggested depending on natural conjugate prior function in addition to suggesting three methods according to robust bayes procedure where the first suggested procedure of robust bayes assumed that there is an extent of belief and to a certain percentage with the researcher (the percentage of the researcher falling into mistake in determining the primary information) where the accurate determination of the primary information has already been made which will be integrated with the sample prospects to obtain bayes estimater As to the second suggested procedure of the robust bayes it treated the problem of the sample prospects contamination or the primary information. Whereas the third robust bayes procedure suggestion had treated the problem of appearance of both problems together - that is inaccuracy in determining the primary information and the possibility of contamination to the sample views or the primary views as well, found a comparison between the studied evaluation methods by using the simulation procedure. It has been arrived to the success of the suggested methods in evaluating the approximate reliability of Weibull distribution depending on the two statistical scales (Integral Mean Square Error) (IMSE) and the (Integral Mean Absolute Percentage Error) (IMAPE).

Abstract: تعد الخصوبة احدى المكونات الرئيسة الثلاثة التي تقرر معدل النمو السكاني الى جانب الوفيات والهجرة. ومن ثم فهي تؤثر في مجمل البنية الديمغرافية والاقتصادية والاجتماعية للسكان وفي هجرتهم وتوزيعهم الجغرافي. وتعد الولادة عاملا بايولوجيا اكثر تعقيدا واصعب دراسة | Fertility is one of the three main components that determine the rate of population growth as well as mortality and migration. And thus it affects the overall demographic, economic and social structure of the population and in their migration and geographical distribution. Birth of biological factor is more complex and more difficult study of global deaths and migration due to the complexity and diversity of influences and volatility. fertility is calculated by the number of children born in a given year to the number of women in the age group (15 - 49) for the same year. And that the birth rate is controlled by several decisions about child - bearing or not.It has been estimated that fertility rates of direct and indirect ways by using the method (Brass and the way Cole - Trassel) In addition to identifying the most important factors that affect the total fertility rate by relying on survey data map of poverty and maternal mortality for the year 2013 for the purpose of calculating the total fertility rate for IraqI province (18 Province) direct method as well as the calculation of the independent variables, which is believed to have an impact on total fertility rates that have used one of the statistical packages which is Spss21 using multiple regression Stepwise factors method is a (family size, average per capita income, per capita spending on health, infant mortality rate, the proportion of poverty, the percentage of married - old (15 - 49), the percentage of illiterate women (15 - 49), the percentage of economically active women, the percentage of women in rural areas, the percentage of women with chronic diseases (15 - 49), change the place of residence (internal migration), the average age at marriage, percentage of the population under 15 years, the percentage of homes equipped with national electrolyte, the percentage of women (15 - 49) in addition to the use of the program (Spectrum) to estimate the total fertility and the preparation of the population and the rate of annual population growth and life expectancy of death as well as the median age for the period (2013 - 2050), according to fertility assumptions (high, medium and low level) for the purpose of population policy in the long run as well as the review of the most important demographic theories that are related to fertility and estimate a record number of fertility in Iraqi , and calculating the national fertility index for the year 2013 in Iraq, which amounted (14%) also were awarded a singles record (INP) of fertility on the basis of considering the 1997 base year
