Re: st: Saving and appending to a file

["Danielle H. Ferry" <dferry@gc.cuny.edu>]

Suppose you had a variable, sample, that took values 1, 2, 3, 4. Then 
perhaps you could do something like this:

forval i = 1(1)4

	tempfile tf`i'

	(estimation) if sample==`i'

	(your matrix stuff)

	outsheet (stuff) using `tf`i''

}

dsconcat `tf1' `tf2' `tf3' `tf4'

Not sure what you are estimating, but in place of your using the 
estimation matrices directly, have you looked into <outreg> or 
<parmest>?
