To clarify the question somewhat, an explicit example may be useful.
In the context of the following nested logit model, we are trying to
generate predicted probabilities of selecting each restaurant (7
different outcomes) for each value of kids (i.e., kids=0, kids=1,
kids=2, etc.).
webuse restaurant, clear
nlogitgen type=restaurant(fast: 1 | 2, family: 3 | 4 | 5, fancy:6 | 7)
nlogittree restaurant type, choice(chosen)
nlogit chosen cost distance rating || type: income kids,
base(family)|| restaurant:, noconst case(family_id)

Thanks for any suggestions.

Caroline
