Abstract: في الكثيرمن الدراسات الطبية والتربوية والسيكولوجية (علم النفس)وعلم الاجتماع نشاهد بان المفردات (subjects) تتكرر تحت مختلف الشروط التجريبية((conditions والتي تسمى بالمعالجات (treatments) وان البيانات المتجمعة من مختلف الوحدات التجريبية تفترض لان تكون مستقل | In many medical , educational , psychology and sociology studies we find that the same subjects repeated under different experimental conditions which called treatments. The collected data from different experimental units suppose to be independent while the observation for the same experimental units will be dependent. The term repeated measures designs is called for this type of data in which the response for every experimental units or subjects is tested or measured under a number of different experimental conditions. Our attention will be on the case of a univariate response variable. There are many procedures for testing the null hypothesis that there is no treatments effects, depends on the number of treatments. either the same subjects are tested under two treatments or tested under three treatments or more. The aim of this study is comparing the tests for nonparametric and parametric methods of repeated measures designs for two treatments through applying the tests on true experiments data. and comparing the tests for nonparametric and parametric methods for three treatments or more, which included two designs which are the complete randomize block design when the ANOVA conditions are satisfied. And the One - way generalized repeated measures model when does not assume specified form of the variance - covariance matrix.Simulation procedures are used in order to compare probability of type one error and power of the test for all methods. In addition , the researcher presented the suggested methods and analyzing the results by comparing them with the other methods for the mentioned designs.

Abstract: ان الخاصية الاساسية لتمييز البيانات المكانية عن بيانات السلاسل الزمنية هي الترتيب المكاني للمشاهدات , وعينات البيانات المكانية تمثل مشاهدات ترتبط بنقاط او مواقع وتتميز هذه البيانات بان ارتباطها يضعف كلما بعدت المسافة وكذلك تتميز بتدرج المكان (( المناطقية | The main property to differentiate the spatial data from time series data is the spatial arrangement of observations and the samples of spatial data represent observations related to points or locations these data are distinguished with the weakness of their connection each time the distance getting far away and the place graduation (location)on the spatial relations of observations are represented in matrix named spatial weights matrix. 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).

Abstract: اصبح المناخ اليوم من الموضوعات الرئيسية المهمة التي تحتل مرتبة الصدارة لدى جميع دول العالم المتقدمة والنامية، لاسيما بعد ان تبين بوضوح مدى التغيرات التي شهدها في العقود الاخيرة. والتي تحدث اما لاسباب طبيعية نتيجة اختلال في توازن النظام البيئي او لاسباب بش | Climate has become a key topic that occupies the forefront of all developed and developing countries around the world, especially after the climate change witnessed in recent decades, These changes occur due to either natural causes as a result of an imbalance in the ecosystem, or human causes such as human economic activities, these changes affected many aspects of life, one of which is the agriculture, including palm cultivation and dates productionThe aim of this research was to study the effect or the relationship between climate and dates production, which is considered one of the most important crops that can be relied upon economically. 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)

When the failure times average value is bigger than one ,so Bayes is the best in estimating the fuzzy reliability for small samples sizes,and FRDP is the best in estimating the fuzzy reliability for sizes of big samples The data which have been taken from the state company for electrical industries of foundation machine Toshiba are used as well after bayes method and FRDP method are applied to estimate the fuzzy reliability,it is noticed that results of both the applied and experimental side are th

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"

Abstract: تستخدم جداول الحياة في مجالات عديدة في البحوث الديموغرافية والصحية وتمثل مؤشرا هاما للوفاة في المجتمع. ويتم احتساب جداول الحياة من بيانات الوفيات لسنة معينة للمجتمع السكاني، لذا فهو يعبر عن حالة الوفاة للمجتمع.وهناك نوعين من جداول الحياة وهي : (جداول الح | Life tables used in many fields in the demographic and health research is an important predictor of death in population. 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.

Abstract: لقد اتسع نطاق الدراسات الاحصائية ليشمل العديد من الميادين والقطاعات ومن ضمنها قطاع السكان، حيث اهتم الباحثون بدراسة مشاكل التعداد والقياسات المتعلقة بقطاع السكان كالولادات والوفيات والهجرة، وذلك لما لها من اهمية كبرى في مجال الادارة والتخطيط.فجاء هذا ا | The scope of statistical studies has been extended to consist many sectors. 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: The goal of the Millennium Development Goals is to promote development by improving social and economic conditions in the poorest countries in Amah at The United Nations Declaration on the Millennium adopted by all Member States in September - September - 2000 of the most important decisions of the General Assembly taken at the end of the last century, as is in a number of commitments aimed at improving the lot of man at the beginning of the third millennium, to conclude that these goals a commitment to development and security, peace and gender equality and the elimination of the multiple dimensions of poverty and achieve sustainable development. It should be noted that most of the goals set by the announcement of the Millennium is not new but derived from the recommendations of global conferences held in the nineties and which was adopted rules and international laws over the past Considered as indicators of the Millennium Development multifaceted, as it contributes in the monitoring of economic and social changes, in addition to the preparation of development plans to improve the status of activities that suffer from a lack of performance at the state level, either at the level of the world are through the provision of indicators for international comparisons, which helps in making decisions on economic, trade and deal with external debt... Etc., and come to the donor countries to take decisions on aspects of assistance, especially emergency assistance and direct form of assistance with time and according to the monitoring of changes in society. And that the goals are the results rather than inputs, where that eating the Millennium Development Goals focuses mostly on the eight goals and objectives of digital and the time frame for achieving them to be a reference to evaluate and monitor the development goals in countries Almokhtlfahomen this sense Akhtaralbages this research and using the system of statistical programs ready SPSS to get to the adoption of analytical methodology using my style factor analysis and cluster analysis in the analysis of these indicators at the level of the provinces where the state acquires Find in the Millennium Development Goals in Iraq is particularly important because of the national decline in the indicators of social and economic development and seek to adopt policies that are in achieving those goals.The research includes five chapters include the first chapter Mekdmaaama and the idea of the Millennium Development Goals, data sources and target research and methodology, and backgrounds of study submitted for analysis of global and cluster analysis and research topic also included Chapter II Showing the Millennium Development Goals, targets and indicators with a brief description on the indicators that have been taken under consideration and an outline of the efforts made in the Arab region in achieving the Millennium Development Goals and the statement of its progress and achievements and its attention to these goals, the third chapter has included explaining factor analysis and cluster analysis used in the statistical analysis included the fourth quarter the interpretation of the results obtained through the study (Urban and Rural Areas), and attended, and Rural Areas [The fifth chapter has included the 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

Abstract: يعد القطاع الزراعي المتمثل بالانتاج النباتي والحيواني في العراق من القطاعات الرئيسة في الاقتصاد العراقي اذ يساهم في تكوين الناتج القومي الاجمالي، ويعد اهمال القطاع الزراعي من المراحل الاولى لظهور بوادر الازمة الغذائية احد اهم العوامل الكامنة وراء تعميق ال | The agricultural sector of plant and animal production in Iraq is one of the key sectors of the Iraqi economy wich contributes to the formation GNP, the neglect of the agricultural sector from the early stages of the emergence of signs of food crisis. One of the main factors behind the deepening food shortages in addition to the lack of succes of agricultural policies in placet o reduce the dependency of food outside and achieve self - suffciency in the country and that any development strategy to achieve food security in the country must take a development in the agricultural sector. To be able to study the changes that happen in the economic phenomena in the future and determining the values of these changes has tob e set up to rely on time - series analysis and that the time series have some numerical values for a statistical index that reflects the change phenomenon for time, and there are some analysis for the series in time zone from the most important statistical methods that are used to predict the values of random phenomena in the future based on what happend in the past, wich helps in future plan for a peaceful economic development and the most important methods are the time series model developed by the Box - Jenkins methodology for a seasonal subseries plot or a spectral plot. The research aims to predict the amount of domestic production and import of all of the Tomato and Chicken, so using the best model of the Box - Jenkins models.And in the search data to quantity of domestic production and import of each tomato and chicken in Baghdad province - Iraq BI - monthly inputs for time zone between January 2012 until december 2014, at rate of 72, the data was obtained from the directorate of Agriculutral - Baghdad Al Reafa - Statistics department. It’s also has been updated into the gretl program. The study consisted of both the theoretical side of the identification of the theoretical foundations of the Box - Jenkins methodology of the time series and after that the applied to the side of the the best model to predict domestic production to quantity and import of each tomato and chicken, after all that the researcher have a some conclusions and recommendations that benefit the peaceful development and plans for the advancement of the agricultural sector and the most important thing is, that the imported Tomatoes and Chickens is more than the locally produced ones, which indicates that the country depends on the imported Tomatoes and Chickens more than the produced.

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.
