摘要：

Likelihood ratio, Wald and Score test statistics were derived for the three discrete distributions, namely Poisson, truncated Poisson and negative binomial, which are widely used in count regression models. These three tests were compared through simulation for the entire three distributions with respect to type-I and type-II error rates and we arrived that likelihood ratio test is better as compared to other two tests.
