I am not (yet) a prof., just a PhD student. 
I am also not an expert on conditional logit, so maybe someone else on the list can answer that.

Even if I were an expert, this post:

has eaten up my daily ``time spent on statalist quota'', and I should now continue writing my dissertation...

Best,
Maarten
