三元混合指数分布的参数估计

Estimation of Parameters of Three-Mixed Exponential Distribution

本文应用EM算法研究了三元混合指数分布在正常应力条件下和恒定应力加速寿命试验条件下,在完全数据场合、Ⅰ-型截尾和Ⅱ-型截尾场合的参数估计问题。

This paper employs the EM algorithm to obtain the maximize likelihood（ML） estimation model under the normal stress life time test with full data or censored samples or type Ⅰ samples or type Ⅱ samples.
