Subject | st: Margeff for postestimation after two-limit tobit produces too many values error |
Date | Fri, 21 May 2010 18:36:27 +0200 |
Dear All, I am relatively new to Stata and have one specific question regarding the command margeff (which I believe is from SSC). I use Stata 10 (Stata/SE 10.1 for Windows, Born 01 Oct 2009). I want to use margeff to calculate the average partial effect (APE) after running a two-limit tobit model (I do not want to calculate the partial effect at the average, which would be possible through mfx). However, if I use the margeff as postestimation command I always get a "too many values" error. Even if I further reduce variables and observations to minimal values the same error persists. The Tobit command, that works perfectly, is: . tobit reaquogescens TCA TTG logbergebenehf logforderungsalter2 lfdverpflichtung sozjurpers smzmph3 smzmph4 smzkf smzinso anzrgvorbeauftragung anzgsvorbeauftragung kderfcens logbearbeitungsdauer, ll(0) ul(1) vce(robust) The margeff command produces the following: . margeff, model(tobit) dummies(TCA TTG \ smzmph3 smzmph4 smzkf smzinso) too many values r(134); I would be grateful for any help. Thanks a lot in advance! -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!
