Hi, Michiel.

First of all, thank you very much for your help. Apollo seems to do exactly what I need. I already installed the package, took a look at the manual and I've been trying to correct specify and calibrate the model.

Right now I'm facing convergence problems. I believe this is due to the ...

Hi experts,

A quick introdution:
I work with transport studies and there's this software we use, PTV Visum, which provides a variety of choice models to distribute travel demand along paths stochastically (route choice). First we setup the utility of the routes (for example, B0 * time + B1 ...

It sure does, Michiel!
Thank you very much for your help, I really appreciate it.

Regards,
Gabriel.

Thank you for your answer, Michiel! I'll definitely take a look at Apollo package.

But, as a more theoretical question, regardless of the software used for estimating the model, when calibrating a model for an unlabeled experiment, is still possible to obtain a R2? I mean, does it still make sense ...

Hi everyone!

I understand that when calibrating a model using logistic regression with data from a binary unlabeled choice experiment, I should include no intercept in the model specification, since there should be no alternative specific constant. I usually use GLM in R to fit my models, and then ...
