The reason you received no replies to
http://www.stata.com/statalist/archive/2009-12/msg00251.html lies somewhere
hidden in the way you asked, not in lack of awareness. Note the FAQ on this
point - which do allow a substantially revised repost...

" The best advice is to rewrite the question so that the key issue is made
as clear as possible but also is stated as briefly as possible."

Betreff: Fwd: st: standard deviation gain calculation with Stata

Hello All,
I would like to know what is the magnitude of standard deviation gain
in years of schooling from residence in metro area from the following
example.
The effect of metroarea (smsa) is : 0.05 from the regression. But how
would I calculate the standard deviation gain given that the average
years of schooling is 13.4.
