比例平均休止时间模型的年龄性质与随机比较

摘要

The proportional expected inactivity time model(PEITM) is introduced and some of its properties are discussed. The results show that reversed hazard rate(RHR) ordering and expected inactivity time (EIT) ordering are preserved under PEITM. The random comparison between RHR and EIT ordering is given with the total variables in different PEITM.%引入了比例平均休止时间模型(PEITEM),讨论了它的一些性质,结果表明反失效率序(RHR)和平均休止时间序(EIT)在PEITM下是封闭的,并给出了不同PEITM中总体变量之间关于RHR和EIT的随机比较.
