Statistical Inference of Weibull Distribution under a Progressive Stress Partially Accelerated Life Testing Model



This paper considers a progressive stress partially accelerated life test model when the lifetime of a product under the use condition follows a Weibull distribution. It is assumed that the progressive stress is directly proportional to time. The maximum likelihood method is used to obtain the estimates of the model parameters. In addition, approximate confidence intervals for the parameters are constructed. A Monte Carlo simulation study is conducted to illustrate the theoretical results of the proposed model.
