The reason is probably that the -mi estimate- dialog box
"inherrited" that option from the normal -regress- dialog box.
I am not that surprised that it doesn't work, because -mi estimate-
seems to work with the returned coefficients as stored in e(b),
and the -standardize- option does not change that matrix.
The way to get those is to standardize all variables in your
model prior to estimating the regression command. The question
now becomes which mean and standard devation do I use, and I
am not sure, though I guess it doesn't matter that much.
Hope this helps,
