Hi Richard,

I would use -estout- with the append option, and regress (or other commands) in the relevant subgroups through loop.
Building on your own example, something like this.....

eststo clear

levelsof a_q,local(l_a_q)
levelsof b_q,local(l_b_q)

capture erase yo.txt

foreach l_a of local l_a_q {

	est clear
	
	foreach l_b of local l_b_q {
		eststo e_`l_a'_`l_b': reg c if a_q==`l_a' & b_q==`l_b'
	} 

	estout * using yo.txt, append collabel(none)

}

If the command you want to use do not return estimate(eg summarize), then you can use -estpost- to make up for for this...
In my experience, it not worth the effort to rely on any output command to give you a perfect final table. IMHO, It's way easier to get the results in the right rows and columns, and then use excel or other spreadsheets as an intermediary before a wordprocessor.

HTH, Jesper

-esttab- and -eststo- are from the -estout- package.

Thanks!
