摘　　要：研究了在不完整分组数据下对离散型未知寿命分布进行估计,从分组截断数据中推导期望失效数量,通过迭代数值方法计算离散型寿命概率分布,从而避免求解复杂的非线性似然方程组,试验说明该方法有效.A novel iterative numerical method for solving the uncompleted censored data statistical prob- lem with unknown discrete probability distributions was presented. In particular, the expectation of the invalid number was deduced from the uncompleted censored data to fulfill the iterations. The experiment results showed that this method was effective.
