[Limdep Nlogit List] klein spady - binary choice

[Arulampalam, Wiji]

I am trying to estimate a binary choice model using Klein-Spady semi
parametric estimator.  Limdep sets the intercept=0.  There is a user
written program in Stata which also sets the intercept=0 (stata program
does not ask for any other restriction).  However, when this technique
is applied, I find the authors setting the intercept=0 as well as
another slope coefficient=1.  I.e. an additional normalisation is
applied.
 
Could someone please tell me what Limdep is doing here?  Is there
another normalisation that is applied here?
 
Many thanks.
 
Yours,
Wiji
