Hi,
I am running a GLM - Poisson Family Identity Link model to show the impact of various predictor values on low birth weight. I am trying to include an offset term to take into account the total number of births. I have the following code:
glm Nlbw PM25cent IncomeScoreMulti NBAME NWhite, family(poisson) link(log) offset(Nbirths)

The output gets stuck looping on iterations. Please can somebody help?
