Bayesian estimation of mean and square of mean of normal distribution using linex loss function

Abstract

AbstractIn this paper, the Bayes estimators for mean and square of mean ol a normal distribution with mean μ and vaiiance σ r2 (known), relative to LINEX loss function are obtained Comparisons in terms of risk functions and Bayes risks of those under LINEX loss and squared error loss functions with their respective alternative estimators viz, UMVUE and Bayes estimators relative to squared error loss function, are made. It is found that Bayes estimators relative to LINEX loss function dominate the alternative estimators m terms of risk function snd Bayes risk. It is also found that if t2 is unknown the Bayes estimators are still preferable over alternative estimators.Keywords: Bayesian EstifnationLinex Loss FunctionNormal EistribdionMeanRisk FbndioDSbnakage Estimation
