Abstract:
In this paper we study Zero Inflated Poisson Distribution (ZIPD),Generalized Poisson distribution with Poisson Distribution (PD). Goodness of fit for two data sets were carried out by the method of the proportion of the zero^th cell. In first data set ZIPD (p=0.854) with parameters (w^{^} =0.56) and (λ^{^}=1.32) and in second data set ZIPD (p=0.520) with parameters (w^{^} =0.430) and (λ^{^}=1.770). It is very logical and encouraging that Zero Inflated Poisson Distribution(ZIPD) provided better fit as compared to Poisson distribution and Generalized Poisson in both the data sets because of more number of zeros.
