The code works fine for me, and Vmatrix is . mat li Vmatrix symmetric Vmatrix[3,3] y2hat x1 _cons y2hat 16314.103 x1 11759.524 14048.737 _cons -813695.51 -807459.49 49450582 In the earlier Robert's example, there may have been no e(rmse) returned after -xtreg- (unlike -reg-). So I am guessing the code produce SOME results... Vince Wiggins says these are right results :)) -- Stas Kolenikov, also found at http://stas.kolenikov.name Small print: I use this email account for mailing lists only. * * 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/
