WebNegative binomial regression is similar to Poisson regression but allows for overdispersion. In fact, Poisson regression is a special case of negative binomial regression, and both give the same results in the absence of overdispersion. However, … WebNegative binomial regression – Negative binomial regression can be used for over-dispersed count data, that is when the conditional variance exceeds the conditional mean.
