you don't say exactly what you want to do, but you can use regression to do a t-test (e.g.); make the values your left-hand-side variable and the only predictors are the dummy for group and the constant; the result for the dummy will then be exactly the same as what you would get from a t-test; you can also correct for unequal variances (vce(robust) option) and to other things, and, of course, regress allows for weights Rich On 4/12/11 3:09 PM, Abelev, Melissa wrote: > Hi - > > I'm trying to do some simple descriptive statistics.
