摘要：

This article considers a shrunken estimator of the exponential mean life θ when a guess value θ0 for θ is available. The estimator is based on the first r ordered observations out of a sample of size n. The estimator is shown to be more efficient than the usual estimators when θ is close to θ0. © 1990.
