So ideally, I would like to loop with -foreach- over a series of dates, but I cannot find the way of doing this. To give you an idea of the kind of problem, here it is in pseudo-code (not working): *** begin pseudo-code foreach t in 1992q1/2000q4 { reg y L.y L.x if tin(1960q1, `t') reg y L.y L.x if tin(`=`t'-20', `t') }

How about this: forvalues t = `=q(1992q1)'/`=q(2000q4)' { reg y L.y L.x if date >= q(1960q1) & date <= `t' reg y L.y L.x if date >= `t'-20 & date <= `t' } where date is your quarterly date variable. -- Brian Poi -- bpoi@stata.com * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
