See
-help postest- and
[U] 20 Estimation and postestimation commands
and try e.g.
sysuse auto, clear
reg pr mpg
reg pr mpg rep78
g restrict=e(sample)
reg pr mpg if restrict==1
reg pr mpg rep78 if restrict==1

Hi-
I am running regressions with several variables, and not all observations have
data on all variables. I run a regression of Y on X, and use say 1,000
observations. Then I run a regression of Y on X and Z, and because not all
observations have Z, I only get a sample of 800 observations. Is there any
way to save the sample from the latter regression, so I can then run the
original regression of Y on only X, but using only the 800 observations that
include Z, without having to go throught the data by hand?
Thanks,
Bill
