I use the mi estimate syntax for my mvn imputations. I find that they always provide standardized coefficients.

Is there an option for unstandardized?

Here is an example of the syntax I am referring to (that always provides standardized coefficients):

mi estimate, dftable: reg HEALTHPLAN1 AGE AGE2 woman2 nonhispblack other hisp SEX2 college_2 continc OWNRENT2 SELFRATED PHYS_ABLE AbilityMean AGEID LONGLIVE prevmarr widowed nevermar faminter_score friendsinter_score

I use this coding to obtain the R-square:
