[Limdep Nlogit List] Error 636

[William Greene]

Kal.  The specification proliferates instruments. The manual section you
quoted
an example with moderate dimensions that specifies thousands of instruments.
The limit in DPD in NLOGIT is 200.  This is (T-1)*(KX + Kf) + KM. I cannot
tell
from your command what these values are. Generically, this is the source of
the
diagnostic.
