Maximum number of iterations

[kenny...@gmail.com]

Hello Prof. Bierlaire,

is it possible to increase the maximum number of iterations?

My estimation is terminated because 1000 iterations are reached when I increase the number of draws for the mixed logit model (or for the Halton draws) leading to parameters that are not really significant compared to less draws.

Thank you!

The “estimate” function takes as argument “algoParameters"

If you use the default algorithm (Biogeme’s Newton’s algorithm with simple bounds), the parameter that you need to modify is “maxiter”

Therefore, the call should look like

estimate(algoParameters={‘maxiter’:5000})
