st: loop with xtmixed

[Flavia Fossati <fossati@pw.uzh.ch>]

Dear List,

I was wondering if there is a possibility to make a fovalue loop with 
the xtmixed command. I tried this way but it doesn't work (option if is 
not allowed):

forvalues j= 1(1)25{
xtmixed vary varx ||GROUP: , mle var covar(un) if idj== `j'
replace b_cons = _b[_cons] if idj==`j'
replace se_cons = _se[_cons] if idj==`j'
}

best,
flavia
