Abstract
The Neyman Type A, Negative Binomial, Poisson with zeros, Poisson and Poisson Binomial with n = 2, 3 were fitted to 35 observed distributions appearing in the literature by the method of maximum likelihood. The fitting methods are discussed and the chi-square goodness of fit is tabulated for all distributions. On the basis of these data, it appears that the Neyman Type A and Negative binomial both have wide applicability. The Poisson and Poisson with zeros gave a good fit to only a small portion of the data.
