On zero inflated generalized Poisson-Sujatha distribution and its applications
Keywords:zero inflated Poisson, excess zeros, goodness-of-fit, moments, Maximum Likelihood
Abstract: A new model called Zero Inflated generalized Poisson-Sujatha distribution (ZIGPSD) is proposed in this paper. Some characteristics of the model were derived and the maximum likelihood method was used to obtain the estimators of the parameters numerically in R-software. Through application to two data sets, goodness-of-fit of the ZIGPSD is tested and fitted count data with excess zeros better than zero inflated Poisson (ZIP) among other distributions.
Key words: zero inflated Poisson, excess zeros, goodness-of-fit, moments, Maximum Likelihood
