Dear all,
I found in NgeneManual112 in page 108 that Ngene ignores any constants in designs for estimating multinomial logit models .
constants that is mean alternative-specific constants but I found information any way that it is must to put in syntax and my model should be no or put alternative-specific constants in syntax.
Design
;alts=cer, ba
;rows=14
;eff = (MNL, D)
;model:
U(cer) =b1.dummy[0 I 0]*I1 [1,2,3] +b2.dummy[0I0I0]*L1 [1,2,3,4] +b3[0]*salarycer[8985,13800] /
U(ba) = b0+b4.dummy[0I0I0]*I2 [4,5,6,7] +b5.dummy[0 I0I0]*L2 [5,6,7,8] +b6[0]*salaryba[11000,15000,18000] $
thank you very much.
