I am quite new to NLOGIT and trying to run MNL model.  While running the model, I am getting this error "Error 1003: A choice label appears more than once in the tree spec." I am unable to figure out that where is the issue? Either in the code for running MNL or in the data?
I have checked the data and in the time series data, only one choice is selected at one instance. Can anyone please help me to resolve this issue? Thank you.
