Richard Palmer-Jones et al.--

Note that -collapse- does not support -svy- for this kind of problem:
"pweights may not be used with sd, semean,..."
But the obvious solution is simply to label the columns of a matrix,
and -egen group, label- before -mean- will give nicer labels:

webuse nhanes2, clear
egen g=group(region smsa), label
svy: mean  bpsystol, over(g)
mat b=e(b)
mat colnames b= `e(over_labels)'
mat li b
