مقارنة طرائق مختلفة لتقدير دالةالمعولية لتوزيع Burr-XII باستعمال المحاكاة.

Abstract

This deals with estimation of Reliability function and one shape parameter (β) of two- parameters Burr – XII , when α(shape parameter is known) (α=0.5,1,1.5) and also the initial values of (β=1), while different sample shze n= 10, 20, 30, 50) bare used. The results depend on empirical study through simulation experiments are applied to compare the four methods of estimation, as well as computing the reliability function . The results of Mean square error indicates that Jacknif estimator is better than other three estimators , for all sample size and parameter values
