WebOct 16, 2015 · From my understanding of the manual, the predict(nu0)-option should calculate the expected number of events at each time interval. Since my data has a lot of overdispersion, I would expect the negative binomial model to provide more accuracte estimates based on my reading of Cameron & Trivedi 's brief introduction on the matter (p. …
WebJul 29, 2014 · Description. xtpoisson fits random-effects, conditional fixed-effects, and population-averaged Poisson models.

Re-produced the model response variable, e.g. Claim_Count, by simulating Poisson random numbers with lambda equal to predicted values from the original model; 2. Repeated the above simulations many times, e.g. 1000, to generate many response series;
