摘要/Abstract

摘要： 基于一类异族分布的混合寿命模型, 给出了在一/二组样本下的I/II型截尾试验下的贝叶斯密度估计方法; 给出了实例; 并提出了一些问题和解决方法.

关键词: 先验/后验密度函数, I/II型截尾, 一/二组样本预测, 区间估计, 异族, 寿命分布, 先验/后验密度函数, I/II型截尾, 一/二组样本预测, 区间估计, 异族, 寿命分布

Abstract: This paper proposes a finite mixture model of heterogeneous population. Bayesian estimates of type I/II censored test with one/two-sample are made for the model;examples of type I censored two-sample prediction are given;questions for further investigated are proposed.

Key words: prior/posterior density function, type I/II censored, one/two-sample prediction, interval estimate, lifetime distribution, heterogeneous population, prior/posterior density function, type I/II censored, one/two-sample prediction, interval estimate, lifetime distribution
