Admirable effort. Your many self-corrections though makes the flow of your explanations difficult to understand.

Hey im trying to run a poisson regression on a set of data, and all my predictor variables are categorical. My Y (Response) variable is count data and i'd like to know how to make a graph that has a model plotted into it. Thoughts ?
