摘要
应用EM算法之ECM算法,研究了混合分布在截尾数据场合下的参数估计问题,并给出具体的算式.说明EM算法是一种行之有效的方法.
The parameter estimation of the mixed distribution under the censored samples has been studied with specific formula by the ECM and EM algorithms, which shows that the EM algorithms is effective. In this paper we use the ECM algorithms of the EM algorithms to present the results for the cases of Mixture Pareto distribution on censored samples.
