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.

ESTIMATION OF COEFFICIENTS AND SCALE PARAMETER FOR LINEAR (TYPE 1) EXTREME VALUE REGRESSION MODEL FOR LARGEST VALUES WITH APPLICATIONS

In this paper we estimate the coefficients and scale parameter in linear regression model depending on the residuals are of type 1 of extreme  value distribution for the largest values . This can be regard as an improvement for the studies with the smallest values . We study two estimation methods ( OLS  & MLE ) where we resort to Newton – Raphson (NR) and Fisher Scoring methods to get MLE estimate because the difficulty of using the usual approach with MLE . The relative efficiency criterion is considered beside to the statistical inference procedures for the extreme value regression model of type 1 for largest values . Confidence interval , hypothesis testing for both scale parameter and regression coefficients
