The overflow encountered in multiply and Inf Std err

[jianbiao wang]

Dear Prof. Bierlaire,

I am estimating the model, and there is a warning: 

The overflow encountered in multiply

Besides, the Std err of a parameter is Inf. 

Does this mean the model cannot convergent?

Thank you very much,

Wang

[Bierlaire Michel]

Biogeme sometimes recovers from overflow, but not always. 

In the HTML report, the reason why the algorithm has been interrupted is reported. You’ll see if it converged or not.
