المستخلص: يوصف هور الحمار بانه من المناطق المهمة ذات الصفات المنفردة , فهو منبع للحضارات البشرية. وقد كان لسكانه دورراياديا في العديد من الازمنة , وهو من المناطق الرئيسه التي عرفت زراعة المحاصيل , وتربية الماشية في نظام زراعي متكامل , وكان ذلك منذ اكثر من 10 الاف | Hammar marsh is described as one of the important qualities of the individual. It is the source of the human civilization has had its leading role in many of the times. One of the key areas identified by the cultivation of crops and livestock in an integrated farming system and that was for more than 10 thousand years. Raised a number of projects to drain the water bodies in southern Iraq, Hammar part thereof, and had a long - term strategic objectives, the most recent was in 1991 during a campaign of wide range of engineering and programmed to dry Hammar. The implementation of this project was the creation of earth dams to prevent the flow of water from the river that feeds the lagoon and then redirected to the Euphrates River is in the Qurnah, at the diversion of the Euphrates from its current location to the east of Nasiriyah, the general course of the mouth was originally Mbzla water intrusion into the Khor Al - Zubair as well as the Arab Valkhalij to the establishment of power between the dirt and eliminate the city of Nasiriyah province to prevent the flow of Euphrates water to Hammar by dams reaches with the same dirt inside the marshes to facilitate drying quickly. This process led to the drying up of more than 94% of the area of al - Hammar marsh, which in turn has led to environmental impacts, economic and social, has been in decline relative to the wealth of fauna and flora, and the growing exodus of the populations in the study. Beyond the year 2003 was dumping Marsh unstructured break the payment of the population, and the opening of the closed barrages, as well as the Ministry of Water Resources and the establishment of the Center for the rehabilitation of the marshes and the taking over control of the recovery of the marshes in collaboration with many international organizations that came to restore life to the marshes. Result of the drying - dumping and re - set of the effects on natural and human resources, which in turn affected economic activity in the whole region. To determine the economic impact caused by the drying process Hammar in the province of Dhi Qar, administrative, and through field study in all its dimensions and form of the questionnaire, interviews and site inventory and analysis of such data, information and descriptive and quantitative research to find a set of conclusions, and most important of which was set for the most important economic implications caused by the drying process, as well as the results of the dumping, and not to encourage the study, most of the people of the return of the marshes and random boarding in favor of non - programmed to believe that he had been in some areas Hammar in the past five years. The presence of agricultural areas, and residential areas in the heart of the marshes, and the creation of a group of influential beneficiaries of the return of the Marsh did not want the past, because they are adjusted with agriculture. The many economic activities, despite the drying up large tracts of Hammar, and their relative importance differed from one village to another. The research also finds that the dumping of partially so excluding land reclaimed for agriculture and the new villages that have emerged in Hammar. And to be gradually and in several stages, each stage determine the period of time, according to plan strategy which would define the nature of investments in the region and the spatial and temporal distribution.

المستخلص: اصبحت الضريبة في عصرنا الحديث جزءا لا يتجزا من حياة كل فرد، فهي تصيب الغني كما تصيب متوسط الدخل، وتصيب صاحب العمل كما تصيب العامل. ومن هنا تبرز اهمية التشريعات الضريبية وحساسيتها لانها تصيب الاغلبية العظمى من المواطنين، مما يتعين على الدولة الاهتمام | Tax became an indispensable necessity today, and it is stable for the independent judgments to make state organization in the rule of money and power. But the tax still in charge of psychological paid deduction may deprive the enjoyment of a portion of its assets and practical considerations here were required to reconcile these opposing interests is therefore necessary that the tax system is based on the foundations of the public treasury to ensure their rights and achieving its goals on the one hand and preserving the rights on the other hand، Citizen and mitigate the impact of tax it. Justice has set up one of the main and most important of these lines and as a key to the integrity of the tax system as well as a target destination for the system. To achieve the goal of the study, were divided in three chapters, which reviewed the conceptual framework of the study, which included on the first topic addressed the concept of tax and objectives, through the four demands addressed first requirement definition and characteristics of the tax, while the second addressed the requirement of a good tax system which By Adam Smith. While addressing the third requirement legal basis to impose the tax, which included financial contract theory and social solidarity. Finally, the fourth requirement was to address the fundamental objectives of the tax and all of the goals of economic, social and political. The second topic included the concept of tax justice and elements, through the three demands came first requirement of explain the concept of tax justice including horizontal and vertical equity. The second requirement address included the elements of tax justice (i.e. the means by which to achieve justice in taxation). This included the four pillars was equal to the tax and tax and public personality and non - duplication. While the third requirement came to distinguish between tax equity and social justice. The chapter II of this study is to review the structure of the tax system in Iraq and income tax legislation in Iraq, through the demands addressed first requirement of direct taxes including income taxes and taxes on capital. The second requirement dealt with indirect taxes, which include taxes and taxes on commodity circulation and behavior.. The second topic of chapter II addressed the income tax legislation in Iraq, where Section Demands to also address the first requirement of the concept of the income tax and the tax position of the Iraqi legislature to either second requirement was to address income subject to tax in the tax legislation in Iraq. The third and final chapter has dealt with justice and the tax achieved in the Income Tax law No. 113 of 1982, as amended, as its first address to the legislature the tax position of the Iraqi staff of tax justice. While the topic of the second look to the future turns out the tax system in Iraq calls for the liberalization of world trade. The study ended with several conclusions and recommendations

These three variables have interacted to form the framework around which the study revolves. Since the banking sector has become an important part of which service sector is made, as well as it represents the basic pivot for the process of building and the development of the economies of countries, the Iraqi banking sector have been taken to be the sample of this study. A nonrandom sample of nine Iraqi banks was chosen, including four state banks (Al - Rafdain, Al - RaSheed, Industrial Bank, and Agricultural), and five private banks (Baghdad, Investment, Middle - East, Darussalam and Al - Warkaa banks). The data were collected from 132 managers working on the first and second levels. A questionnaire form was used as the main instrument of data - collection, in addition to personal interviews, and some reports, and statements about the banks. In order to process these data, a set of statistical methods such as (mathematic means, standard deviation, percentage, Spearman correlation coefficient, Mann - Whitney test coefficient). Upon the measurement and analysis of the study variables and testing the correlation and the exchange interaction, the study comes up to a group of conclusions among which the high level of variables of the study samples, another finding is that there is correlation relationship between the two independent variables (the market orientation and organizational learning), in addition to the existence of moral effect for the mutual relationship in business performance. While it turned out that the effect of each variable become weaker in business performance individually. On the other hand, it turned out that there is no differences in the opinions and viewpoints concerning the sample among the state and private companies and the sub - dimensions. A set of recommendations were put on the basis of the findings of the study. Finally, the researcher suggested some future studies that enhance aspect.

LCCA is a method to find the correlation coefficients between two groups of data involved different variables by calculating Eigenvalues of the block Variance - Covariance ( or correlations) matrix of the two groups, and their associated Eigenvectors as weighted to each set group data to find a series of canonical varieties to each group set. The correlation coefficient between the first canonical of each set which corresponding to the maximum eigenvalue called first canonical correlation. LCCA have some properties that should be exists to work with it , the importance one is the multivariate normal distribution of each set of data , and the linearity relationship between these variables. The research studied also the Kernel methods with some Kernel functions to establish the symmetric Gram matrix by inner Product of the original data set of each group, and then using the same approach as LCCA but in this case with a semi positive matrices instead of positive defined matrices in LCCA , this mean with combine between classic CCA and Kernel methods which is called Kernel Canonical Correlation Analysis (KCCA). The advantage of this knew method to discover more relationships between sets of variables. The goal of this research to show how to obtain the optimal weighted that when multiplicities by the original sets of data will maximize the canonical correlation coefficients. Some simulation experiments were applying here in order to find that KCCA methods exceed the assumptions of LCCA, the canonicalcorrelations that come from this new method is greater than from classic method, with consideration propose two mixed kernel functions.In application side, we suggested a true parameter ? in kernel function instead that used in simulation.

المستخلص: The importance of planning increased in general and production planning in particular and its role maximized over years, being the basic pillar that are depended in planning the branch activities concerned, and a method for organizing economic in different countries and it has its basic rules and methods the matter that motivates us to study it in details.The men who are responsible for production planning face the problem of choice between the number of available possibilities and all these problems are solved according to the personal approbation and practical experience, but when the choice problems become complex, it becomes difficult to depend on experience and experiment only to reach to the right choice ( the ideal ) and then the new mathematical methods mush be used to solve these problems.Accordingly, the idea of focus on linear programming is originated which became one of the methods that are most used in the field of different establishments production planning by showing the effectiveness and efficiency of this method in expressing the production plans with quantitative method, and if me look deeply and in auditing way to the different production processes if me find that it is possible in many situation, to get certain product in many technical methods by using varied production methods, that in the industrial applications, there are a large number of industries that allowing to substitute certain types of items with others.the deep analysis of production methods shows that the production methods that use the same methods cannot be of one or similar characteristic or descriptions but They one Different from each other in one characteristic or other, and thus, the research find that in spite the first and quick view of production process may lean an impression that for each product a defined method for its production or it requires the using of certain resources, but the fact that there are a large number of solutions that are possible for each production question beginning from choosing the items that are necessary for production and ending with the method of products transforming and distributing, and practically, the persons who are responsible for production planning in the establishment face different production problems that require the ideal and suitable solution within the group of possible solution that the best possible solution when the production resources are limited is the solution that secures the larger possible result from exploiting these resources.The process of finding the ideal solution is very complex, as the quantity of possible solutions is very cage, the matter which makes the process of choosing the ideal solution among them by comparisons need along time and a big effort and then the work becomes impossible practically and here the vole of mathematical programming came which provide the men who are responsible on production planning in the establishment with mathematical method, especially the method of linear programming which allows the finding of ideal solution for production and economic questions without the resourcing to the studying of all possible solutions and their comparison.

المستخلص: 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.

المستخلص: In this study, the light had been shed on the relationship between of indicators stock market and business cycle in selected countries ,the study has been divided into three main chapters in order to test the validity of this hypothesis and achieving the aims of this study. The first one forms a conceptual and ideological of study and included three basic section. The second chapter dealt with Analyzing framework of study included two basic sections. While , chapter three has concentrated on the measure and analysis of the Feed back between stock market and business cycle. The study sample consist of six countries : USA, Mexico, Thailand, Malaysia, Korea, Egypt. It uses annual data covering the period (1983 - 2006).By using the Hsiao causality test has been used determine the direction of causality between indexes of stock market and business cycle.This study has yielded (concluded) many results from the theoretical and mathematical (econometric)First : "the conclusions of the theoretical aspect1 - Are the economies of industrialized countries over time, as with cases of depression and recovery, which affect to economic activity, and companies know that these conditions are strongly influenced by cycle companies, with sales booming with economic recovery and stagnation and decline in the shares of these companies know the stock prices rise as the periodic during the phase of prosperity and decline during the recession, the success of the investor depends on the type of the shares so to correct timing of the purchase 2 - The existence of a relationship and mutual influence between the work of primary and secondary markets, as the evolution and breadth of the work of the primary market leads to the development and expansion of the secondary market, through the development, diversification and expansion of new releases through the primary market, which offer the possibility of development and expansion of the secondary financial market activity, and using those issues later in their dealings, and in accordance with the clear understanding of this difficult chapter of the work and the development and expansion of these markets. 3 - financial derivatives is one of the most important features of modern financial developments during the last decade of the twentieth century, and these tools provide payments derived from other assets may be real or financial assets to cope with fluctuations and crises that have affected financial markets, which were used as tools to hedge against fluctuations in stock prices and rates interest and exchange rates. 4 - A shift in the characteristics of economic cycles, after the Second World War, becoming shorter courses "and less in terms of the duration of the decline in production or in terms of rates of deterioration in the indicators of economic activity and the disappearance of the global economic crisis as characterized by the unequal international distribution among countries capital, in addition to the lack of synchronization occur in those countries, but that this situation would be different during the eighties of the twentieth century and in the context of globalization has become the crisis overtaking the limits of all countries, whether developed or developing. 5 - The recurrence of financial crises and the breadth and speed of transition in the light of financial globalization is a controversial and attention to result in the damaging of a comprehensive and unexpected is not limited to the financial sector, but extends to other sectors and the effect of high economic costs have a negative effect not only in a crisis but extended beyond the borders to other countries. 6 - at the basis of the relationship between the performance indicators for the stock market situation of economic activity, the movement of stock prices is an important indicator to predict the economic cycle as they move in the opposite direction to the movement of bond prices, and up to the maximum level before the arrival of economic activity to the top of the recovery and up to lowest level before the arrival of economic activity to the bottom of the recession. 7 - The East Asian crisis occurred because of the big gap between the real sector and financial sector, which increased with the application of financial liberalization policies in the countries of East Asia, which has made the capital looking for a quick profit by speculating in the financial sector which has seen significant expansion and irresponsible, and take exercise role Parasitically hindering the process of economic growth, which has affected of the development the real economy and shot back, for the extent of the crisis and its spread from the center of the crisis (Thailand) It was during the economic vulnerability of financial markets and the integration of the global financial system. Through any channels of foreign trade and financial markets.8 - The degree of vulnerability of the Arab countries the financial crisis America is different from country to country, depending on the degree of economic openness and the degree of financial and economic development, countries are opening up the high and the Arab Gulf countries in particular will be more affected by and through the channels of oil and the dollar exchange rate stability. Second : the conclusions of the quantitative aspect 1 - The analysis showed that the standard linear model is the best expression of the models and the reality of the stock market in the United States. 2 - analysis showed that the standard non - linear model (Logarithm double) is the best model to reflect the reality of the stock market in each of the (Mexico, Thailand, Malaysia, South Korea, Egypt) 3 - The results of the United States signs an agreement with the estimated parameters form the logic of economic theory in terms of a direct correlation between stock market indices and the state of economic activity, except the number of companies that have demonstrated an inverse relationship because of the merger that took place between listed companies in the market. 4 - show a causal bilateral Feed Back casualty between stock market indices and the economic cycle, there is no impact of the market shares of economic activity is economic activity towards the stock market, which confirms the existence of a significant impact to the stock market on economic activity in the United States, as these are the efficiency of the market high. causal bilateral Feed Back casualty between stock market indices and the economic cycle, there is no impact of the market shares of economic activity is economic activity towards the stock market, which confirms the existence of a significant impact to the stock market on economic activity in the United States, as these are the efficiency of the market high. 5 - it seems that there is a causal relationship bilateral Feed Back casualty During the time lag between the first indicators of the stock market (the market index, the turnover rate) and the state of economic activity (economic cycle) in Mexico, in the direction of the market value, volume and the number of companies to the economic activity of the stock market, when considering the case of economic activity as the dependent variable.With the direction of the relationship when the stock market indicators as dependent variable of the independent variable (the case of economic activity) to the stock market indices, except the market value.6 - The results of measurement in Thailand and a positive relationship between stock market indices and the state of economic activity (economic cycle), it was determined to test the causal relationship that the two - way and at the failure except for the first time the number of companies. 7 - shows the measurement results on Malaysia as in accordance with the logic of economic theory, which pointed to the existence of a relationship between the soft variables, and confirmed through the test of causation and the existence of feedback between the stock market and the state of economic activity.8 - The results of South Korea in line with the logic of economic theory, which revealed the presence of a direct correlation between the stock market and the state of economic activity (economic cycle), which was evident from the test of causation as the two - way, except the number of companies.

From this point was the good behind this research in reaching robust estimators of canonical correlation analysis that can be achieved through the study of some robust methods such as (estimators - M, estimators - MVE, estimators - MCD and estimators - S).for the failure of the classical methods of estimation of canonical correlation analysis at containing data on the ratio contamination (outliers), that leads to the derivation of incorrect covariance matrix consequently to correlation matrix and a series of relations between the incorrect variables. Therefore the robust methods were used in the calculate of covariance matrix which would lead to robust matrices to robust canonical correlation analysis.In order to achieve the objectives of the research, it was divided into four chapters.The first chapter included the introduction, purpose of search and review of literature, the second chapter tackled the theoretical aspect of the robust methods in canonical correlation analysis as well as some of the important concepts, the third chapters deals with the application aspect in which tow types of applied studies were made, The first one uses the simulation method to compare among the studied methods of estimation in canonical correlation analysis and detect the best of the estimator depending on the two statistical measurements bias mean and mean square error which renders the minimum MSE of canonical correlation analysis, the second study uses the truthful data to verity the performance in a practical actuality.Finally, the fourth chapter included the conclusion, recommendations to which the researcher has arrived. In general it is regarded that MCD estimator is the best in the estimation of canonical correlation analysis in comparison with the other studied methods of estimation.

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

Dollarization is a result of the financial liberalization , it is a situation of deviation in the monetary equilibrium of macroeconomics , leading to the correlation financial liberalization and the recent trends of monetary policy based on the indirect means.2. Dollarization ,as a feature of the financial liberalization , poses challenges against monetary policy , which exposes it to currency crisis in countries suffering insufficient financial markets and weak local currency.To test this hypothesis and achieve the study's objectives , this study divided into four chapters.Chapter One deals with Dollarlization : The historical and theoretical roots.Chapter Two explains monetary policy effectiveness , and Factors influencing it under the financial liberalization.Chapter Three offers reflections of Dollarlization in monetary policy efficiency. While Chapter Four specialized with analysis and measurement the causal relation between the economic disequilibrium ( imbalance ) indicators and Dollarlization measurement indicator for both Egyptian and Iraqi economy for (1991 - 2006 ).The study ends with some conclusions and recommendations. The most important of conclusions are : 1. The causal relation trend from the economic imbalance indicators to Dollarlization measurement indicator for Egyptian economy , as well as the economic imbalance indicator for Iraqi economy.2. Under an environment of currency subistitution , the policy of making the exchange rate as a tool to fix the inflationary expectations , is efficient in De - Dollarlization , in spite of the cost of this policy in the field of lower Central Bank reserves and / or extra burden on public expenditures.While the most important recommendations are : 1. To reduce Dollarlization and its risks , it is necessary to have dual approach , i.e. , it discourages the use of foreign currency and promotes the attractiveness of local currency as a mean of intermediation.2. Economic stability is an important aim to remove Dollarlization , but it might not be enough to reverse it (De - Dollarlization ). So , it requires other procedures , such as liberalization of local interest rate , establishment of a competitive payments system using local currency , and development of local Financial tools , those are also steps that can help the De - Dollarlization phenomena

The study was applied on a sample of (140) managers distributable among many managerial levels members of ( board of directors, general managers or delegated managers, department managers, division managers, and unit and office managers ). The study has used the questionnaire as a main tool for collecting the data, and information in addition to the personal interviews and some annual reports related to companies. The study has tried to test a number of major and minor hypotheses related to the relation and regression among the variables of the study, and the differences among the companies in the main variable of the study for the purpose of answering all the questions related to the problem of the study and reaching the established objectives. For the purpose of processing the data and the information related to the study the researcher has used tested by non - parametric statistical tools as : Mediator, Scope, False limit factor and Regression. The study has reached to several conclusions, such the availability of the main three variables in a high level in the all companies under consideration, the availability of significant correlation among them, and significant effect for each of the organizational innovation and organizational change in the organizational effectiveness. And these results came appropriate with the hypotheses related to this aspect. The researcher has presented a number of recommendations, such as the necessity of encouraging and building organizational innovation by the companies managements and applying that in their different policies and programs related to the human resources. In addition to that, it is necessary to adopt the organizational change culture and training the managers on its skills and traits. Farther more, the necessary of the dependence of companies in executing its operations and the treatments with their customers, market, and on the standards and indicators that a achieve the effectiveness and success in their functions in different means and techniques.

المستخلص: تعد البيانات الاحصائية ضرورية عند دراسة اغلب ظواهر المجتمع ومنها الظواهر الاقتصادية والاجتماعية والنفسية الخ كون تحليل تللك البيانات باستخدام الاساليب الاحصائية توفر للباحث او متخذ القرار حول الظاهرة المدروسة قاعدة من المعلومات الضرورية لتسهيل عملية اتخاذ | The statistic data is important to study most of phenomena as economical , social , psychological phenomena..etc. The analysis of this data via the statistical methods gives the researcher or the decision maker more information about the studied phenomenon to make the suitable decision. The data availability needs to limit a mathematic model which represents them by the researcher and to put in consideration the type of the available data. One of the these data is panel data which can be defined ( that they are repeated measurements to the studied phenomena for N from the cross section and for T from the time series ) which can be represented by one of the model ( fixed effect model or random effect model ).Most of the studies exposed estimation of the chosen model parameters by using the classical methods as GLS and FGLS methods , whereas this research touches on the Bayesian methods to estimate parameters , especial regressive model (panel data) ,depending on the priors distributions ( non informative prior dist. and conjunct prior dist. ) and to compare them with ML method to chose the best ones for estimation and choosing.After doing two practical applications in the research ,we obtained findings. ML method was the most significant for estimating the model parameters for the fixed effect model and pooling model. Bayes method which depends on non informative prior distribution , got the second grade.When using Bayes method depending on prior distribution used in the research to estimate the fixed model parameters when the cross sections number are little to get multivariate - t posterior distribution , and if it is used with random effect model we get multivariate normal after making asymptotic expansion with existing of a loss function of the weighed squired error.
