Poisson models for counts make the (very) strong assumption that the conditional variance is equal to the conditional mean. In this talk, we look at a recently-proposed extension of the Conway-Maxwell-Poisson distribution that can handle both overdispersed and underdispersed counts. The exponential family form of these distributions leads to particularly simple estimation and inference procedures from both a frequentist and Bayesian point of view.
