مقدرات الاختبار الأولي المقلصة ذات المرحلة الواحدة لمعلمة القياس للتوزيع الأسي

A preliminary test single stage Shrinkage (PTSSS) techniques is used for estimation the scale parameter q of an exponential distribution when a prior knowledge about q is a available in the form of initial estimate q0 of q. It is proposed to estimate q by a testimator  that is based upon the result of a test of the hypothesis H0 :q = q0 against the hypothesis HA :q ¹ q0 with level of significance a. If H0 is accepted we take , where the weighting factor  is a function of the test statistic for testing H0 or may be constant such that . However if H0 is rejected we take , where  and  is the classical estimator of q (MLE). Choosing the weighting factor , (i =1,2) appropriately, an expression for the mean squared error (MSE) and Bias of  are derived and comparisons are made with classical estimator () in the sense of efficiency and last earlier studies.

Compare between simex and Quassi-likelihood methods in estimation of regression function in the presence of measurement error

       In recent years, the attention of researchers has increased of semi-parametric regression models, because it is possible to integrate the parametric and non-parametric regression models in one and then form a regression model has the potential to deal with the cruse of dimensionality in non-parametric models that occurs through the increasing of explanatory variables. Involved in the analysis and then decreasing the accuracy of the estimation. As well as the privilege of this type of model with flexibility in the application field compared to the parametric models which comply with certain conditions such as knowledge of the distribution of errors or the parametric models may
