st: Poisson and post estimation analysis

A couple of years ago I ran some poisson regressions on publication and citation data and found some post-estimation commands that enabled me define comparisons between groups. For example, based on the use of certain procedures available under Stata, I was able to observe that being a graduate of the two particular types of graduate programs, compared to a third type, increased the expected number of published articles by 132 percent and 110 percent respectively, and the expected numbers of citations by 114 percent and 96.5 percent respectively. Unfortunately, although I can recall the procedures were available under Stata, perhaps as a .do file, I cannot recall names, etc. Anyone know the procedures I am talking about? Any help would be greatly appreciated. Thanks. * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
