[Limdep Nlogit List] panel data model

[Philip A. Viton]

I'm trying to estimate a panel-data version of the binary logit model 
for a sample of votes of judges on the courts of appeals. In this 
case, my groups are the 12 circuits; within each circuit I have a 
large number ( > 2000) of individual votes. But when I try to 
estimate the model I get error 548, referring to an abnormally large 
group-size variable (which I suppose it is).

Have I run up against a  built-in limitation of limdep (v 8), or have 
I set things up wrong? (Of course, I can estimate the fixed-effects 
model by hand, by setting up dummy vars for the circuits, and not 
worrying about the panel specification).

Thanks!
