| 摘 要： | 基于逐步增加定数截尾样本,对累积失效模型(简称CE模型)下,Weibull分布恒定应力加速寿命试验(简称恒加试验)进行了Bayes统计分析,利用Gibbs抽样给出了该模型的Bayes估计。最后,通过模拟例子表明Bayes估计有效而实用。

| Abstract: | Bayesian analysis of Weibull distribution with progressive Type-II censored sample of the constant stress accelerated life tests under CE model is proposed. Bayesian estimation of the model are obtained using Gibbs sampling. Finally, the Bayesian estimation is demonstrated through simulation example that it is most effective and efficient method. |
