As a very crude solution, you could try something like

* do-file begins here
set more off
* Load the data
	sysuse grunfeld, clear
	matrix tval=J(2,2,.)
	matrix colnames tval = tvalue modNr
* Loop over all models (neglected here) and store the
* results of interest (e.g. tval):
	tsset fn yr, yearly
	xtreg I F, fe
	matrix tval[1,1] = _b[F]/_se[F]
	matrix tval[1,2] = 1
	xtreg I F C, fe
	matrix tval[2,1] = _b[F]/_se[F]
	matrix tval[2,2] = 2
* create a variable from the matrix and drop the
	drop _all
	set obs 2			// number of rows in J
	svmat tval, names(col)
* only keep the models which are of interest
	drop if tval<10

* do-file ends here

Like this you get a list with all interesting models.

If your main interest lays in obtaining the relevant variables in the
model you should probably be better off using -stepwise- together with
-regress- after having manually performed the within transformation.

I hope this helps.

Kind regards,
Ingo
