Oops, I changed the example code but not the description. Sorry. Wendy: I suggest that you use Ben Jann's -gsample- command, from SSC. The following example draws observations from 3 cateogries of rep78. Adapt to your own needs. You need the -preserve- and -restore- commands, because -gsample- keeps only the sampled observations.
