Actually, -xtivreg2- is written so that if there are no endogenous regressors, you can use it the way you use official -xtreg-. Thus *does work xtivreg2 ys k n, fe --Mark-----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Martin Weiss Sent: 10 April 2009 21:46 To: statalist@hsphsun2.harvard.edu Subject: st: Re: single exogenous variable, panel data estimation problem <> With only an exogenous variable, the whole "IV" stuff is redundant. You can use -xtreg- directly...
