Problem Note 49703: Results may be incorrect when STRATA and POSTSTRATA variables are the same
The results produced by PROC SURVEYMEANS might be incorrect when any of the variables specified in the STRATA statement are also specified in the POSTSTRATA statement.
To avoid this problem, create one or more duplicate variables as necessary to use in one of the statements. If the original variable is character, make sure original and duplicate variables are both unformatted or that they have the same format with no trailing blanks.
