在逐步Ⅰ-型混合截尾寿命试验下,分别采用EM算法和简单数值迭代法讨论了广义指数分布的极大似然估计和矩估计.最后利用Monte-Carlo方法给出数值例子,比较了这两种估计的优良性。
The maximum likelihood estimates and estimate of moment of the parameters in the generalized exponential distribution are discussed under progressive type-I hybrid censoring by EM algorithm and simple numerical iteration separately. Finally, a numerical example is given by Monte- Carlo method to compare the two estimations.
