Let X1,, X, Be A Random Sample Of Size N From This Truncated Poisson Distribution (i) Show That The Sample Mean X Is A Biased Zero-inflated data indicates that the data set contains an excessive number of zeros. The word zero-inflation is used to emphasize that the probability mass at the point zero exceeds than the one allowed under a standard parametric family of discrete distributions. Gupta et al.,1 Murat & Szynal,2 Patil & Shirke3 have contributed to estimation and testing of the parameters involved in Zero 2019-01-06 The zero-truncated multiplicative-binomial distribution is derived and investigated. In particular, the maximum likelihood estimators of the parameters and their asymptotic variance-covariance matrix are obtained. The simulation procedures for generating data from zero-truncated multiplicative binomial distribution using R-software and are given.

zero-truncated candidate distribution. Mullahy (1986) has developed another type of distributions that deal with the preponderance of zeroes.
