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
