Abstract
[Abstract]: This paper estimates the mean of a normal distribution in presence of non-sample prior infor- mation regarding the value of the mean. We de¯ne the unrestricted estimator (UE), restricted estimator (RE), p-value based restricted estimator (PRE) and p-value based preliminary test estimator (PPTE) based on the sample, prior information, p-value of an appropriate test and combination of all them respectively. The relative performance of these estimators is studied on the basis of bias and mean square error (MSE) criteria. Both analytical and graphical com- parisons are investigated. If the p-value is reasonably small, the PRE almost uniformly over performs the UE and PPTE, regardless of the level of signi¯cance.
