Generation of overdispersed poisson count data (vs gamma poisson)
Hello, I would like to reconcile the parametrization used in the Random Gamma Poisson(lambda, sigma)
with the over-dispersion parameter as estimated in generalized linear model platform. Take for instance the attached table. Here the generating function is Random Gamma Poisson(exp(1+3*:X1),10)
Running glm with poisson/log + overdispersion I obtain: Overdispersion = 6.09. Is there any way to link...
