Abstract

Progressive-stress accelerated life testing in which the stress on an unfailed item increases linearly with test time when the time transformation function is a version of the inverse power law is considered. The approach is nonparametric in that not many assumptions are made about life distribution. A testing pattern is introduced, and it is explained how to draw inferences from progressive stress tests. An estimator of life distribution at the usual stress level is proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
