Accelerated Life Testing - A Pragmatic Bayesian Approach.

In this paper a model is proposed for accelerated life testing which differs from those considered in the past. Our model does not reuqire the usual assumptions about the failure distributions and the accelerated functions. Our approach is Bayesian, and depends on the estimation of ordered failure rate functions at different stress levels. Since our model is nonparametric, and our approach is quite pragmatic, our results should be of use to engineers working on accelerated life tests, and biometricians involved in carcinogenic experiments.
