PARETO-GEOMETRIC DISTRIBUTION
摘要
Abstract
In this paper, we introduce a new lifetime distribution with decreasing failure rate, that is two-parameter Pareto-Geometric distribution which is obtained by compounding a Pareto and a geometric distribution. Various properties are studied and the existence and uniqueness of the MLE of parameters are discussed, the MLE of parameters are gained by the EM algorithm and their asymptotic variances and covariances are obtained, also.关键词
