Hi,
For GLM models, I know that the response variable Y must be from a member of the exponential family of distributions, but can some one explain how you would actually make it be a poisson distribution for example? (if you were building a GLM model)
Are the chosen link function and error distribution independent to the distribution for Y? So I guess making the distribution for the error function poisson doesn't cause Y to be Poisson.
I think my confusion is coming a bit from a mis-understanding of GLMs in general so any help would be much appreciated!
