Hi Sven,
Thanks for the advice, but the problem for a stated preference discrete
choice model is that estimation depends on the choice sets seen by the
individuals. Say each individual sees a choice set with three
alternatives. The estimation routine needs to know the three and which
of the three was selected. STATA allows this. I don't see that here.
Well if the three alternatives are different from one observation to the
next (why are they always three then, though?), this is beyond me,
sorry. Probably not doable in gretl (apart from programming it up
yourself with gretl's scripting language, of course...).
good luck,
sven
