Abstract

This paper we suggest some one & two stage shrunken estimators for
reliability function of exponential distribution by using complete data .The
shrunken factor is variable we find it by minimizing mean squared error for
The suggest estimators .The bias, mean squared error and relative efficiency
expressions are derived theoretically and assessed practically by using monte-
carlo simulation . The results show the suggested estimators have better
performance then classical estimators .
