Abstract

The research leading to the estimator for shape parameter  in failure censored samples from two parameter Weibull distribution, when a prior information contains a guess interval containing the parameter .In this paper we recognized two estimators for parameter . The first is of type linear estimator and the other is Shrinkage estimator, with comparison between them using Minimum mean square error (MMSE) and percent Relative efficiency. The scale parameter  can be estimated by M.I.E using any iterative approach such as, simple Iteration or Newton-Raphson method, Also we propose an estimator combining both MLE and Shrinkage estimator for parameter , by using a linear combination of them.
