[Limdep Nlogit List] NLogit crashes with I simulate a nested logit model

[John C. Whitehead]

Hi all,

I'm trying to simulate a nested logit model: 3604 cases and 4 alternatives.
When I try the simulate command NLogit crashes and I get the following error
message:

limdep.exe - Application Errror

The instruction at "Ox5f402181" referenced memory at "0x0000000004". The

I am able to simulate a conditional logit model with the same data and a
nested logit model with different data.

Any ideas?

Thanks,

John Whitehead
