Hi all,
I'm trying to find a way around a problem. The code below results in an error since svy cannot by combined with by. I cannot think of another way to get the equivalent result I need, however, since the mean I'm attempting to calculate must be run using svy.
Any ideas?
Code:
foreach varname of varlist `PAYMENTVARS' {
generate `varname'PANAVG = 0
by DUPERSID PURCHRD, sort: svy: replace `varname'PANAVG = mean(`varname')
by DUPERSID PURCHRD: keep if _n==_N
drop `varname'
}
Error:
svy may not be combined with by
r(190);
Regards,
A
