Re: st: Weighted random effects -rfregk-

I downloaded and am trying to use the "rfregk" command with

wrong? Any ideas regarding the fix?
OK, I looked at the ado file, and it appears to me that a couple of
the lines got zapped somehow, as if somebody tried to edit it but
screwed it up. Specifically, there are line breaks in the wrong
places and extraneous comment code. Look for the little bit of code
that starts with if "`weight'"!="" and replace it as follows:
if "`weight'"!="" {
by `ivar': replace ``i'' =
cond(`dup',sum(`w'[_n-1]*``i''[_n-1])/sum(`w'[_n-1]),``i'')
}
else {
by `ivar': replace ``i'' = cond(`dup',sum(``i''[_n-1])/(_n-1),``i'')
}
Before I do that, I get the same error you do. After i do that, I
get the following:

. rfregk invest kstock [aw = mvalue]

If you have trouble, I can also email you the revised ado file if you want.
