Dear Nick,
Thank you. I came up with the following code:
*********************
egen group=group(age_cat)
sum group ,meanonly
foreach i of num 1/`r(max)' {
stmh hivstatus if group ==`i'
}
****************
How could I make this to do the same thing for other variables such as age_cat?
Bets wishes,
Nick
