st: predicted probabilities for Poisson regression

[Rudy Fichtenbaum <rudy.fichtenbaum@wright.edu>]

I am brand new using STATA having used SAS for many years.  I am trying 
to run a poisson regression and then get the predicted probabilities. I 
found the program pprob where you put the command  pprob , mean() n() 
graph.  This works fine but I am not sure where I get the mean value. I 
know how to calculate the mean value in SAS but I can't figure out how 
to do this in STATA.
