This endogenous variable is interacted with dummies for race, but all appear in the parenthetical portion of -xtivreg-. I want to show the marginsplot for race, taking into account the interactions, but I'm afraid the -xtivreg- is not recognizing my endogenous variable as time-varying. > > Maybe I'm doing something wrong with the IV estimation. ?? > > Diego > > -- > > David Diego Torres, PhD > NSF SBE Postdoctoral Research Fellow > Houston Education Research Consortium > Rice University > 6100 Main Street, MS-28 > Houston, TX 77005 > Phone: 713-348-2984 > Email: ddtorres at rice dot edu > > > ---------------------------------------- >> Date: Mon, 30 Dec 2013 14:05:26 +0000 >> Subject: Re: st: Graphing a function (setting coefficients at their means) >> From: njcoxstata@gmail.com >> To: statalist@hsphsun2.harvard.edu >> >> If I understand you correctly, you need to do the manipulations before >> and outside -twoway function-. -twoway function- contains no >> intelligence to do with previously estimated models.
