Extra Poisson
Posted: Wed Nov 23, 2011 12:44 pm
Can someone tell me what the difference is between extra poisson and negative binomial? What is the difference between the assumptions and estimation techniques if I use the "extra" option under the nonlinear tab in MLwiN?
Also, do I not get a DIC with the extra poisson results but I get a DIC with the regular poisson results?
