Dear All,

 

First may I thank you for your response regarding the fixed parameter, I was
wondering the same. 

 

Second, using an LC model in two segments, how do I work out the membership
likelihood based on the sociodem data that I have using limdep?

 

I am using the coding below, with fe, nf and goody being my individual
related socio dem data.

 

NLOGIT

;LHS= CHOICE, CSET, ALTI

;CHOICES=A,B,SQ

;lcm

;pds=6

;pts=2

;MODEL:

    u(A)= WORK*WORK1+START_a*STARTa+start_b*startb+LABOUR*LABOUR1+
GOOD*GOOD1 + BAD_a*bADa + BAD_b*badb

/

    u(B)= WORK*work1+START_a*STARTa+start_b*startb+LABOUR*LABOUR1+
GOOD*GOOD1 + BAD_a*bADa + BAD_b*badb

/

    U(SQ)=ONE+fe*female+nf*non_farm+goody*good_y   $

 

When fixing coefficients I used the rst code as suggested. This I presume
fixes the coefficients to zero as opposed to normalised them? 

 

Many Thanks

 

Phil
