Dimitri, you may want to look at Long & Freese's -spost- commands, and in 
particular their -listcoef- and/or -prchange- commands.  Their book, which 
you can get from the Stata bookstore, is great.  I have brief discussions 
of their commands at

Long & Freese talk about various types of standardized coefficients, but I 
am not sure if they are the same thing you have in mind or not.
