Abstract:
الحمد لله والصلاة والسلام على رسول الله سيدنا محمد (صلى الله عليه وسلم) وعلى اله وصحبه وسلم اما بعد... تناول البحث استخدام انموذج انحدار اللوجستك في التجارب الحياتية باعتباره موضوعا على قدر من الاهمية , وان هناك شروط يجب ان تتوفر لغرض اجراء التحليل بال | This study deals with using the logistic regression model in the bioassay which is considered an important topic and there must be assumption which should be satisfied in order to carry out analysis in the classical methods ( Weighted least squares method and Maximum likelihood method ) as success normal distribution assumption for errors , when one assumption of normal distribution is fail or outlier in data this lead to taking the fail decision concerning the problem needed so be studied.Here lies the importance of applying robust methods (M method and R method ) in the bioassay of the quantal response because the Robust estimated has little response and little effects of outlier.To state the contents of this thesis it was divided into four chapters. The first chapter included the introduction and the aim of this research work. The second chapter included the theoretical part where we stated the estimated methods for the logistic regression model and the Robust methods. The third chapter went through the practical part of this research work. Finally Chapter four went through the conclusions and recommendations of this research work. As well as the future studies, which have been proposed regarding this research. of the most important results the study reached is the efficient M method and R1 method for two robust in estimator the parameters dose model of the quantal response
