Dear Professor Michel,
I'm trying to model a traffic choice modeling using Biogeme. The model I want to build is the nested logit model.
Below is an example of the dataset I used:
There is a socioeconomic variable named HINC (which stands for household income). I want to include this variable in the nested logic model and assume it exerts different impacts on each alternative. I was wondering is below the right way to include HINC in the utility function?
Another question is: what is the meaning parameter MU? Is this the logsum parameter?
