April 2010 16:56 An: statalist@hsphsun2.harvard.edu Betreff: st: RE: using dates with inrange() You could use something like ... if inrange(date, mdy(8,15,1999), mdy(8,14,2000)) Nick n.j.cox@durham.ac.uk David Souther I'm trying to figure out how to create a variable that coded according to whether it falls in certain time periods in my dataset. So, I've got data like input date "03/29/2000" "04/21/2001" "08/07/2002" "09/01/2001" and I format the dates with replace date = date(date, "MDY") format date %td but I want an indicator that is 1 if the dates are in the range Aug. 15, 1999 to Aug. 14, 2000 and indicator = 2 if in the range Aug. 15, 2000 to Aug. 14, 2001 and so on, but I cannot figure out how to get inrange() to work (or some other method to create this indicator): generate ind = . replace ind = 1 if inrange(date, 15aug1999, 14aug2000) * * 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/ * * 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/
