[Limdep Nlogit List] (no subject)

[Gursimran Kaur Saini]

Hello,

I am trying to develop a mode choice model using a  nested Logit model using NLOGIT 6.
I am running into the following errors:
- I am unable to load my data file onto NLOGIT (with about 250,000 observations), when I create another file with a part of the data, I was able to import it, but not the complete file.
- Number of choices not equal to the number of alternatives”

I’m not sure what I am doing wrong.
Here’s the code I am using

Nlogit
;Lhs=CHOICE

;Choices=CarD,CarP,Bus,Walk,Bike,MSM
;Tree=Trips{Private[Car(CarD,CarP),MSM],Public[Bus],NMT[Walk,Bike]}
;ias=Carp
;Show Tree
;start=logit
;Maxit=100
;Model:
U(CarD) = a_CarD+tt*TT+vo*VOwn+emp*EMPD+Inc*Income+popn*PopD /
U(CarP) = b_CarP+tt*TT+vo*VOwn+emp*EMPD+Inc*Income+popn*PopD /
U(Bus) = c_Bus+tt*TT+vo*VOwn+emp*EMPD+Inc*Income+popn*PopD /
U(Walk) = d_Walk+tt*TT+vo*VOwn+emp*EMPD+Inc*Income+popn*PopD /
U(Bike) = e_Bike+tt*TT+vo*VOwn+emp*EMPD+Inc*Income+popn*PopD /
U(MSM) = e_MSM+tt*TT+vo*VOwn+emp*EMPD+Inc*Income+popn*PopD $

Please help me resolve.
thank you,
