I'm trying to estimate a multinomial logit model but in some choices only alternatives from a subset of all possible alternatives can be chosen.
At the moment I get around it by creating "dummy" variables to mean the alternative is not available and let it estimate this coefficient as highly negative. Is there a better way to do it?
