基于EM算法的II型混合删失数据的参数估计

Estimation of Parameters based on Type-II Hybrid Censored Data by EM Algorithm

    摘要
  • 摘要: 本文基于EM算法, 对于II型混合删失数据, 分别在Gamma和正态寿命分布族下进行了参数估计, 并且推导了协防差矩阵. 最后给出了几个很好的数值例子, 对本文的结论进行了诠释.

     

    Abstract: In this paper, we estimate parameters of gamma life distribution and normal life distribution by EM algorithm based on Type-II hybrid censored data. The covariance matrices are derived as well. Some numerical examples are also presented for illustration.
