Yet another way to get intepretable results from such a model
(though I prefer the -glm- or -poisson- route already
mentioned by Austin Nichols) is to use the -eform- option in
-regress- and interpret the coefficients as ratio changes in
the geometric mean of the dependent variable. See:
Roger Newson (2003) Stata tip 1: The eform() option of
regress. The Stata Journal, 3(4): 445.
