[Limdep Nlogit List] Equality constrained latent class model

[S Tarfasa]

Dear all,

I need your help on how to estimate attribute non-attendance using equality
constraint latent class model.I have seven variables(6 attributes and a
monetary variable) i.e., X1,X2,X3,X4,X5,X6 and X7.


I have 9 classes to use(PTs=103).

class 1 none of the attributes igored
X1 is ignored
X2 is ignored
X3 is ignored
X4 is ignored
X5 is ignore
X6 is ignored
X7 is ignored
all is ignored.

Constraining the coefficients of the ignored attributes/price,how do put
the syntax using NLOGIT 5.?

Thank you in advance for your help
