How can you standardize/z-transform variables after imputing missing values using proc mi?

PROC STDIZE

Thanks for your reply. Is there some trick to using proc stdize on imputed data? The resulting mean is very close to zero when I use proc mi and then proc stdize (for example, mean=-8.19047E-16), but it isn't exactly zero as I'd expect.

There is no trick. Your mean is zero except for roundoff error. Nothing to worry about.
