摘要
本文首先指出了在寿命试验中一个非常重要而又容易忽视的事实,也即初试产品和替换产品的寿命同为二参数指数分布的有替换寿命试验的数据分析将完全不同于替换产品的寿命为仅含刻度参数的分布的寿命试验的数据分析。然后借助于更新过程的理论给出了前一种寿命试验的极大似然估计。模拟例子表明这种估计是很有效的。
A very important but easily ignored fact in life foisting is pointed out, viz. the life data analysis of the life testing with the original and the replacement items having this same two-parameter exponential distribution is quite different from that of the life testing with the replacement items having a ones-parameter exponential distribution. Based on the theory of renewal process the maximum likelihood estimators of the parameters of the former are given.
