[Limdep Nlogit List] wald test for linear restrictions

[scolombo at ugr.es]

Dear all,

I need to know whether I can specify a variable as continuous or as
discrete in a latent class choice model.
I used the following estimation code:

NLOGIT;Lhs=Card; Choices=A,B,C
;rhs=D,E,F,G
;pds=newpnl12 ;maxit=500
;Lcm=factor1,factor2,factor3,factor4
;pts=2;prob=ClasP; utility=clasUt
;Test: b(6)-b(7)=0,b(6)-b(8)=0,b(7)-b(8)=0
;Test: b(14)-b(15)=0,b(14)-b(16)=0,b(15)-b(16)=0$

I does not work and the output warnings me that:

Error   109: ;CLS/RST - error in syntax.  Check specified constraints.

I tried to simplify it, even in a simple conditional logit model, (where I
just use the first set of restrictions)it does not work and repeat the
same.

Can someboty spot where the error is?

Thanks.
