st: Scaling of variables

["Achmed Aldai" <Hauptseminar@gmx.de>]

Hi

I have to do an analysis with balance sheet data of several firms (gvkey) and want to scale some of the variables by total assets(at). E.g. total liablities, earnings, and so on. Is there a way that I can do this with one command and not do it for each variable since I have around 40 and that would take a lot of time. Still I dont have to scale all of them by total assets. The company (gvkey) and industry specifications for example should stay unchanged.

gvkey           at           lt
1001            1120         231
1001            1230         312
1210            57           32
1210            67           25
1354            789          560
1368            650          500
1481            1230         900
2930            21           30
3201            234          213
3201            256          220
3210            267          320
4510            4335         3214


Thank you very much for your help.
