摘要：
A well-known estimator for the shape parameter of a two-parameter Weibull distribution from a failure-censored sample involves a preliminary test of a null hypothesis concerning the parameter. Efficiency of the resulting testimator varies with the chosen level of significance of the test. We present an alternative procedure with a higher efficiency over this for each significance level under various circumstances. Appropriate choice of significance level is also discussed. © 1990, Taylor & Francis Group, LLC. All rights reserved.
