st: Poisson and post estimation analysis

[celdjt@umich.edu]

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.
