Abstract

. We consider a stage life testing model and assume that the information at which levels the failures occurred is not available. In order to find estimates for the lifetime distribution parameters, we propose an EM-algorithm approach which interprets the lack of knowledge about the stages as missing information. Furthermore, we illustrate the implementation di ffi culties caused by an increasing number of stages. The study is supplemented by a data example as well as simulations.
缺少阶段信息的阶段寿命测试——一种EM算法
. 我们考虑一个阶段寿命测试模型,并假设在哪个级别发生故障的信息是不可用的。为了找到生命周期分布参数的估计,我们提出了一种em算法方法,该方法将关于阶段的缺乏知识解释为缺失信息。此外,我们还说明了由于阶段数量增加而导致的实现困难。本研究以一个数据实例和仿真作为补充。
