Hi Maarten,
This is a test reply to see whether I can reply to your message and have
it post without pasting the syntax I used from your example.
Best,
Frank

This is one way of getting standardized coefficients after multiple
imputation:
*------------------- begin example ----------------------------
sysuse auto, clear
ice rep78 price mpg, m(5) clear
foreach var of varlist rep78 price mpg {
gen double z`var' = .
}
forvalues i = 1/5 {
foreach var of varlist rep78 price mpg {
sum `var' if _mj == `i'
replace z`var' = (`var' - r(mean)) / r(sd) if _mj == `i'
}
}
mim : reg zprice zrep78 zmpg
*--------------------- end example ---------------------------------
Hope this helps,
Maarten

Thank you. Your thoughts were helpful, and I also hope that
an experienced person with the -mim- command might offer
some insight.
Best,
Frank

You can find a general recipe for recovering the beta
coefficients here:

As I have never used -mim-, I am highly reluctant to
endorse any calculation in connection with it. AFAIK, P.
Royston, its author, does not post to the list regularly, so
he is unlikely to comment, either. But there are probably
more experienced listers who can step in...
Note that my -mata- code was way too complicated as you
have now revealed that you are a beginner. Sorry about
that...
