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 :))
