On the Performance of Least Squares Estimators in Type II Censored Accelerated Life Tests.
Abstract
In context of the analysis of accelerated life testing experiments where items are tested under more severe stress conditions than those arising in normal use, the least squares approach is noted for its simplicity. Expressions are derived for the asymptotic efficiency of the least squares estimators when the failure time data are type II censored. Applications of the general results are made to the Weibull and exponential models and the loss of efficiency is investigated in relation to the severity of censoring and the nature of spread of the design points.
