DOUBLE STAGE SHRINKAGE BAYES ESTIMATOR FORTHE VARIANCE OF NORMAL DISTRIBUTION WHEN THEMEAN IS UNKNOWN BY USE THE SHRINKAGE FUNCTIONWEIGHTED OF FIRST SAMPLE SIZE .
SHRINKAGE
ESTIMATOR
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.
