Hi all,
I'm estimating a conditional logit with 150 possible alternatives.
However, over these 150 possible alternatives only 134 are chosen.
When estimating in Stata with clogit, should I include as my choice set
the 150 possible alternatives or only the 134 that are actually chosen?
I have some doubts about whether the estimation procedure takes into
account alternatives that are not chosen by any chooser.
Thanks in advance,
Rodrigo
