摘要
This paper considers the estimation of reliability when the lifetimes are exponentially distributed. Three different versions of shrinkage estimator are considered when a prior estimate of the mean lifetime is given. Simulation results suggest that some shrinkage estimators have smaller bias and mean squared error than those of the maximum likelihood estimator.
