I'm looking for a way to fit a conditional logit on grouped data in R. I have multinomial choice counts with response- and individual-specific variables. Unfortunately, the expanded dataset would be too huge to work with it. Thus I can't use most of the packages I know, mlogit
for example.
I discovered vglm
from the VGAM
package but it doesn't work if one explanatory variable is missing for a response category.
Has someone tried something similar in R ?
Thanks!
