介绍了混合广义指数分布的失效模型,并运用EM算法给出了模型在完全数据情形下的参数估计方法,最后用数值例子说明了EM算法对本文模型的有效性.
In this paper a failure model of mixed generalized exponential distributions (MGED) is introduced and its estimators for all unknown parameters under full data are obtained by means of EM algorithm. The final simulations show EM algorithm is very effective to our model.
