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: 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.

Abstract: نتيجة للحروب التي مر بها العراق على حدوده الشرقية ,والقصف الذي تعرض له خلال حرب الخليج (1980 - 2003) اصبحت العديد من الاراضي تحتوي على الالغام والمخلفات الحربية ,مما ادى الى ظهور مشكلة عدم استثمار الرقع النفطية التي تقع تحت المساحات الملغومة ,حيث تم استعم | The wars rate that Iraq pass it at the eastern borders, And the bombing he faced during the gulf war (2003 - 1980 ) many areas became contain Mines and remnants of the war. 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.

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

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.

Abstract: البيانات العنقودية تظهر في الكثير من العلوم الاجتماعية والصحية والسلوكية. وتتميز هذا النوع من البيانات بوجود الارتباط بين مشاهداتها. وممكن التعبير عن العنقدة من حيث العلاقة بين القياسات على الوحدات ضمن نفس المجموعة فان النماذج الاحصائية تحتم على حساب الار | Cluster data appears in a lot of social, health and behavioral sciences. 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: حيث تم استعمال اختبار (Cochran, Mc Nemar, Ireland & Kullback, Stuart, Bhapkar, Ireland & Ku & Kullback) على بيانات ذات معالجتين وكل معالجة بمستويين المتمثلة ببيانات مرض ضغط الدم ولدوائين وكل دواء بمستويين (ملائم وغير ملائم) ومن خلال الجانب التطبيقي تم الو | In this dissertation the study have concentrated on the use of repeated measurements tests of catcorigal data, where we used (Cochran, Mc Nemar, Ireland & Kullback, Stuart, Bhapkar, Ireland & Ku & Kullback) tests on two treatments data, and every treatments with two levels which represent raised blood pressure data, and for two medications, each medication with two levels (appropriate and inappropriate), through the practical aspect, we concluded that the ratio of response for the two medication are the same. Also we used (Ireland & Ku & Kullback, Bhapkar, Stuart) tests on data with two treatments, each treatment has more than two levels that represent data of fifth grade (High school) for Arabic text book through years (2001 - 2004) in sumer high school, in which the first treatment represents the students grades in mid term exam, and the second treatment represented the student grades in final exam, through the practical aspect we gained an equivalent results in the previously mentioned methods (in which the students levels in mid term exam equivalent to that in final exam). We also used (Ireland & Kullback, Cochran) tests and weighted least squares (WLS) tests on three treatments data in which every treatment has two levels that represents data of student in the same grade, and in the same years for English text book in which the first treatment represents the first term average, and the second treatment represents the student's grade in mid year, and the third treatment represents the average of second term. And for two levels (Pass and failed), through the applicative of these test on these data we concluded that the level of any given student in first term is equal to the level in mid year and it's also equal to that in second term.

So measured estimated pez S*(t) for survival function S (t) is the conditional expectation function S*(t) =E[S (t)/X].It has been used approximated methods to measure them because It is hard : to measure the complementary of numerator and denominator in a mathematics form by using Bayes method. One of these methods is the method of the searcher ( Lindley) while the other method was return to ( Tierrney and Kadon).In addition to methods formerly to estimate the survival function; the searcher has used the Shrinkage method. While she used the maximum likelihood method as a usual method for those which did not depend on the primitive information because the estimated thing had fixed quality.So, all this to make the comparison between these methods and the oldest one through simulation style by Mont - Carlo to get new estimation which carried the wanted qualities in the perfect estimated to get specific results : to choose the suitable estimation method.The searcher hade made the bayes (lomax distribution survival function) as the lindley manner was the best among the other manners to estimate lomax distribution survival function ,on general ;while the manner of the maximum likelihood method was the best manner among to other estimated manners for tiny simple size on private.

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
