Abstract

In this paper, we consider some finite mixtures of intervened Poisson distribution and study some of their properties. The identifiability conditions of the mixture models are derived and parameters of these mixtures are estimated by method of factorial moments, method of mixed moments and method of maximum likelihood. Further, this mixture distribution is fitted to some real life data-sets and compared with mixtures of positive Poisson distribution.
