I doubt your syntax which has response and panel identifier both equal
to x.
But something like
gen predicted = .
egen group = group(id)
su group, meanonly
forval i = 1/`=r(max)' {
tempvar pred
var <whatever> if group == `i'
predict `pred'
replace predicted = `pred' if group == `i'
drop `pred'
}
should get you closer to where you want to be. See also.

8/05 Is there a way to tell Stata to try all values of a
particular variable in a foreach statement without
specifying them?
