Models Comparison for Step-stress Accelerated Life Testing
In this paper, we compare four commonly used models for a step-stress accelerated life test. It is found that the CE model, the LCE model and the TRV model are identical when the underlying distribution belongs to a log-location-scale family, which is usually use in describing the lifetime of a product, with the log-location parameter varying on the changing stress and the log-scale parameter keeping constant. A likelihood criterion is recommended to test the TFR model and the CE model under the Weibull distribution.
