More generally, Johannes' original post included the question "why does this error occur"? I think the answer is two-fold: 1. From Stata's point of view, the error is the user's, in trying to run a program when the executable is not in sync. 2. More positively, -xtivreg-'s programmers guessed that some users would try to do that, so that they wanted to explain gently to such users what the problem was, rather than -xtivreg- crashing messily when it tried to use something not available. Nick n.j.cox@durham.ac.uk Johannes Geyer Thanks Martin for the hint. I guess you are correct. Now I realize that it is really the printing not the estimation that produces the error. Because the vector e(b) has all the estimated coefficients in it of course. And all other estimated results are produced as well. When I type ******************************** qui xtivreg n l2.n l(0/1).w l(0/2).(k ys) yr1981-yr1984 (l.n = l3.n), fd ******************************** I don't get an error message.
