Abstract:

Parameter estimation of mixed generalized
exponential distribution model under grouped and right-censored data
is considered by using EM algorithm in this paper. The estimation
formulae are obtained and some simulations are presented to
illustrate the proposed method. Finally, a set of medicine data is
analyzed.
