[Limdep Nlogit List] Re: Limdep Digest, Vol 25, Issue 4

[Santa Dutta]

Dear Mr.Danielis,

As per my understanding you are trying to constrain the
normal distributed random parameter. For that you need to specify the
level of constraint.
Replace "o" by 0.5, 1,1.25 etc as follows:
*; Fcn=variable name (n,0.5)
; Fcn=variable name (n,1)
; Fcn=variable name (n,1.25)*
. Else, if you donot wish to constrain your parameter, just use
*
; Fcn=variable name (n)*



 Regards,

S.S.Dutta
