Dear LIMDEP users,
I am trying to setup a Nested logit model as follows;
NLogit
;Lhs= choice, cset, altij
;Choices = C, B, T, O, N
; tree = Yes(C,B,T, O), No(N)
;Model:
U(C) = bc + b11*T1+b12*T2 /
U(B) = bB + b21*T1+b22*T2 /
U(T) = bT + b31*T1+b32*T2 /
U(O) = bO + b41*T1+b42*T2 /
U(N) = bN + b51*T1+b52*T2
; utility = u1 $
All the variables (e.g., T1 and T2 and all others) are individual
specific. It does not vary with alternatives. Given this my questions
are;
1- Is it possible to estimate/ identify all bs of the model (for
the four alternatives)
2- If the answer to first question is yes, then how the code should
be for the utility model specification?
Any suggestion/direction will be highly appreciated. Many thanks.
Kind regards,
Muhammad
