[Limdep Nlogit List] Error: Model is too complex

[Sabir, M. (Muhammad)]

Dear all,

 

 I am trying to run  the following model ;

 

 Nlogit

; LHS = Choice, Cset, Altij

; Choices =  A, B, C, D, E, F, G, H, I 

; Tree =   AA(A,,B, C, D, E, F, G, H), BB(A, B, C, D, E, F, G, H), CC(I)

; Start = Logit

; Show 

; Model :

U(A)   =  B10+B11*X/

U(B)   =  B20+B21*X/

U(C)   =  B30+B31*X/

U(D)   =  B40+B41*X/

U(E)   =  B50+B51*X/

U(F)   =  B60+B61*X/

U(G)  =  B70+B71*X/

U(H)  =  B80+B41*X/

U(I)   =  B90 [0]  

;Ivset : (CC) = [1.0]

;Maxit=150

;Utility = U1 $

 

 (All X are individual specific variables and are constant over
different choice). 

 

I get the following error message:  

 

Error  1020: The model is too complex - too many parts. Table overflow.

 

I could not find this error message in LIMDEP Reference Guide 9.0. 

 

 Can someone explain what does this error means or  what is wrong here ?


 

Many thanks. 

 

Kind regards,

Muhammad
