The EM Algorithm of Parameter Estimation of Weibull Distribution under Type-I Censoring Sample

Shen Pei-ping

Abstract

The paper deals with Type-I Censoring sample by EM algorithm,in which some information is usually neglected.The study has got the iterative solution of the parameter of Weibull distribution.Moreover,a comparison of EM algorithm and maximum likelihood estimation is made.It is a clear result that the EM algorithm is superior to maximum likelihood estimation.
