Simulation with Pythonbiogeme

[Benjamin Heldt]

Dear Biogeme users, dear Michel:

I am using Pythonbiogeme to estimate a location choice model and I would be happy for some help with my Validation analysis.

I know that BisonBiogeme can be used to simulate and calculate utilities, probabilities and standard errors based on a previously estimated model by applying sample enumeration.

Is that possible too in Pythonbiogeme too, and if so, how can I retrieve the simulated utilities?

Is there a tuorial/code on that?

I would be very grateful for an answer asap.

Thank you so much and best regards

Benjamin

Not only it is possible, but it is also much more flexible. You basically need to define a list of expressions that you want to calculate and report for each entry in the data file. And when you need a derivative (for elasticities, for instance), no need to provide the formula, Biogeme can calculate derivatives fro you.  

Look at the online example http://biogeme.epfl.ch/examples/swissmetro/python/01logit_simul.py
