DOUBLE STAGE SHRINKAGE BAYES ESTIMATOR FOR THE VARIANCE OF NORMAL DISTRIBUTION WHEN THE MEAN IS UNKNOWN BY USE THE SHRINKAGE FUNCTION WEIGHTED OF FIRST SAMPLE SIZE .

Abstract

In this articale we depend on Shrinkage function of Bayesian estimator for the variance of normal distribution when the mean is unknown weighted by Shrinkage factor like afunction of first sample size to obtain the double stage Shrinkage Bayesian estimator for the variance when using include double stage Shrinkage estimator formula.
