Re: st: Loop over all unique values of a variable
Thanks Maarten, everything is clear now! Although I have Stata8.2SE it gave me an idea what keyword to look for. So for all Stata8 users:
*--------------- begin example -------------------
sysuse auto, clear
recode rep78 1/2 = 3
levels rep78
foreach lev in `r(levels)' {
di _n _n as txt "rep78 = " as result `lev'
reg mpg wei if rep78 == `lev'
}
*---------------- end example --------------------
