本文利用Gibbs抽样法得到了CE模型下指数分布场合步进应力加速寿命试验的多层Bayes参数估计,最后通过模拟比较表明多层Bayes估计比最大似然估计更加有效而实用。
This paper gives a Hierarchical Bayesian parametric estimation based on Gibbs sampling of the step-stress accelerated life testing of exponential distribution under CE model. Finally, we demonstrate that Hierarchical Bayesian estimation is more effective and useful than maximum likelihood estimation by comparison of simulation.
