A Preliminary Test Procedure in Life Testing

Journal of the American Statistical Association, 1974
This article provides a new estimator of the exponential mean life which makes use of a preliminary test of hypothesis on the scale parameter for certain life test situations where a guess of the parameter value is available from past studies. Expressions for the bias and mean square error of the proposed estimator are derived.

Tests for the mean residual life

Biometrika, 1975
SUMMARY In this paper we develop tests for alternatives representing decreasing mean residual life and the property 'new better than used in expectation'. The decreasing mean residual life test statistic, V*, is new, and critical constants and a large-sample approximation are obtained to make the test readily applicable.
