المستخلص: تبقى عملية التقدير لمعلمات انموذج الانحدار من المواضيع المهمة رغم كثرة ما كتب عنها من خلال البحوث والدراسات وهذه الدراسات تختلف باختلاف الاساليب المتبعة في عملية التقدير سواء كان هذا الاسلوب تقليدي او بيزي او تبعا للتوزيعات التي يتم توظيفها في عملية التق | the process of estimating the parameters of regression model , is still still one of the important subjects despite of the large number of papers and studies written in this subject , these studies are differ in techniques followed in the process of estimation , whether they are classic or baysian , or according to the distributions applied in the estimation , and which are available about some of the parameters of regression model.In this thesis , two different distributions are applied ( Beta , Exponential )in estimating different sample sizes and then making a comparison among the classic estimation techniques represented by (OLS) method , and the method of applying one distribution or two (u.d) , and the baysian methods by providing the distributions themselves.By using the simulation technique , results has been obtained to provide the researcher with the image to clarify the best method in the estimation technique.This thesis come in four chapters : The first chapter contains the introduction and the background of the subject.The second chapter contains the theoretical basis of the estimation methods, when one or two distribution are applied in estimation technique whether is the classic or baysian method, it also contains all that related to derivation process to obtains the estimation style.The third chapter contains , a display of the practical side and also a display of the results of the simulation process used to reach to the best techniques of estimation.Finally, the forth chapter contains the conclusions and recommendation as well as future studies.
