And another problem I incurred with conditional logit (sorry for sending so soon again, I had this problem a few days ago but apparently I did not sent the email in a correct way).
While using clogit combined with xi, I obtain the error "(not concave)" after almost each iteration. Besides, each iteration takes ages. Did I define too many variables or are the variables too much correlated?
Cheers, Peter
