The EM algorithm of parameter estimation of Weibull distributions under type I censoring samples. (Chinese. English summary) Zbl 1212.62009
Summary: This paper deals with type I censoring samples by the EM algorithm, where some information is usually missing. The study obtains an iterative solution for the parameters of Weibull distributions. Moreover, a comparison of the EM algorithm and maximum likelihood estimation is made. It is a clear result that the EM algorithm is superior to maximum likelihood estimation.
