[Limdep Nlogit List] NLOGIT command or data construction

[William Greene]

Hiroshi.  The message means exactly what it says.  For observation 
(group), 278 the LHS variable does not consist of (0,0,...,1,0,0...).  This
usually occurs when your counter, in this case, CSET, is incorrect, so
the data set is not correctly blocked for the estimator.
