[Limdep Nlogit List] Utility Functions ASC and Sociodem Interactions

[Phil James]

Dear All,

 

I am currently doing some choice modeling from experiments where I have no
status quo described, but respondents did have the status quo/no change
option in the experiment. The experiments were traditional unlabeled choice
experiments otherwise. 

 

I was wondering when using the command lines as below how I could interact
the socio dem variables with the ASC?

 

NLOGIT

;LHS= CHOICE

 ;CHOICES=A,B,SQ

;MODEL:

u(A, B)= asc + P_X*X + p_y*y + p_z*z /

U(SQ)=0$

 

 

Many Thanks

 

Phil
