Nick, 1. It is weighting. Add [fweight=NUMBER] to your commands in the appropriate place, typically immediately before the comma that signifies options. See -help weight- for more on this. 2. Try this: . recode NAT (1=100) (2=0), generate(NAT2) . table COUB COUNTRY, contents(mean NAT2) format(%9.0f) If you want percentage signs and/or Excel-friendly output, try installing and using Ian Watson's -tabout- from SSC. A nice PDF help file is also available. . ssc install tabout David -- David Radwin Research Associate MPR Associates, Inc. 2150 Shattuck Ave., Suite 800 Berkeley, CA 94704 Phone: 510-849-4942 Fax: 510-849-0794 www.mprinc.com > -----Original Message----- > From: owner-statalist@hsphsun2.harvard.edu [mailto:owner- > statalist@hsphsun2.harvard.edu] On Behalf Of Nick Petschek > Sent: Thursday, May 26, 2011 5:57 PM > To: statalist@hsphsun2.harvard.edu > Subject: st: How to use dataset where each record relates to a specific > number of observations (weights?) > > Dear Statalist, > > I have two (basic) questions.
