Dear R users
I have been looking for functions that can deal with overdispersed poisson
models. According to actuarial literature (England & Verall, Stochastic Claims
Reserving in General Insurance , Institute of Actiuaries 2002) this can be
handled through the
use of quasi likelihoods instead of normal likelihoods. However, we see them
frequently
in this type of data, and we would like to be able to fit the model anyway.
If it is possible, would you please show me how to find the corresponding
package and utilize them?
Best Regards,
Chi Kai
