Also note -stepwise- and -nestreg- as similar commands. A related question
would be how one could capture model selection criteria (adjusted R square)
for the regressions run on the covariate combinations thrown up by
-selectvars-:
**********
cap ssc inst selectvars
sysuse auto, clear
selectvars headroom trunk length
foreach v in `r(varlist)'{
regress mpg `v'
}
**********
The -postfile- suite of commands is an obvious solution, but I imagine there
are more convenient ways to do it...

Subject: st: Find all subsets of variables
Dear all,
i want to find out all subsets of a given set of variables for model
testing. As an example:
A set of variables var1 var2 var3 var4 should give me:
var1 var2 var3 var4
var1 var2 var3
var1 var2 var4
var1 var3 var4
var1 var4
var1
var2 var3 var4
and so forth.
I would like to test all possible model configurations. Is there a
command in Stata, which could be convenient to use?
Thank you for any help,
dirk
