Hello, I would like to incorporate a bivariate Poisson distribution into my model. I couldn’t find the possibility for bivariate Poisson in Pymc, so I need to model it myself. According to Wikipedia : A simple way to generate a bivariate Poisson distribution X_{1},X_{2} is to take three independe…

Could you talk a little more about why you’d want to have correlated Poisson variates? Is there a specific reason you wouldn’t want to model (\log \theta_1, \log \theta_2) as draws from a bivariate normal? This construction is used quite a bit more frequently.

Thank you for your help!
That is a great resource that I did not find before.
Much appreciated
