The Best Estimate of Reliability in the Exponential Case

Abstract

The commonly used estimate of reliability in the exponential case, i.e., the maximum likelihood estimate, is shown to exert a strong negative effect on reliability calculations because of its bias. A minimum variance unbiased estimate is then derived using a theorem of Blackwell and Rao.
