摘要
研究了当寿命分布为几何分布时,观测数据分组与可能删失的情况下的参数估计,利用EM算法求出了参数的MLE估计,在平方损失下得出了参数的Bayes估计,并应用近似Beta分布加权和的方法得出了参数的近似的Bayes置信下限.
This paper presented the maximum likelihood estimation by EM algorithm,Bayesian estimation under the square loss function.Subsequently,we obtained the approximate lower limit of Bayesian estimation by using of weighted sums of Beta distribution for the parameter of geometric distribution with grouped and censored data.
