• A COMPARATIVE STUDY ON ZERO-TRUNCATED POISSON-LINDLEY AND QUASI POISSON-LINDLEY DISTRIBUTIONS

Abstract

In this paper, zero-truncated quasi Poisson-Lindley distribution has been introduced and investigated its statistical properties including general expression of probabilities and moments and any other related measure and compared this distribution with zero-truncated Poisson-Lindley distribution. The problem of estimation for estimating the parameters of zero-truncated quasi Poisson-Lindley distribution has been also discussed. Application of this distribution to real data is also given and fitting have been compared with zero-truncated Poisson-Lindley distribution to see its goodness of fit.
