| Abstract: | Without introducing accelerated life equation, this paper provides a method and the results for exponential success failure type data under step stress ALT(accelerated life testing) with Bayes theory. The results include the posterior density and Bayes estimate of distribution parameter under normal stress in a quite simple format. Finally a numerical example is given. |
