广义逆指数分布元件的可靠性分析

摘要

Based on type-II hybrid censored samples,the maximum likelihood estimators of the unknown parameters is derived. The approximate confidence intervals for the parameters based on the s-normal approximation to the asymptotic distribution of MLE are constructed. Bayes estimates using Lindley's approximation method and Tierney & Kadane's approximation method are developed for estimating the unknown parameters. Finally,Monte-Carlo simulations are performed to observe the behavior of the proposed methods.%在II型混合截尾样本下,得到了广义逆指数分布未知参数的最大似然估计.利用最大似然估计的渐近正态性构造了参数的渐近置信区间,运用Lindley's逼近方法和Tierney&Kadane's逼近方法计算出了参数的Bayes估计.最后,运用Monte-Carlo方法对上述估计方法结果作了模拟比较.
