This paper demonstrates that the conditional negative binomial model for panel data, proposed by Hausman, Hall and Griliches (1984), is not a true fixed-effects method. This method—which has been implemented in both Stata and LIMDEP—does not, in fact, control for all stable covariates. Three alternative methods are explored. A negative multinomial model yields the same estimator as the conditio...

The study investigated the robustness of Quantile regression count data over negative binomial regression, when there is overdispersion and presence outlier. made use a complete with 30% missing which was imputed using Multiple Imputation by Chain Equation (MICE) in R also an outlier injected into during imputation values. Regression Negative Binomial estimates were compared their model fits co...
