Draws are defined outside the MonteCarlo operator

[Saptarshi Sen]

Dear Prof. Bierlaire,

Hope you are doing well.

I have performed a mixed logit model on Biogeme and it is running fine. I used Halton draws for the random number generations. However, when I am trying to estimate the elasticities or the market shares I get the following error -

"The following draws are defined outside the MonteCarlo operator: {'EC_B', 'ASC_B_Rand', 'EC_T', 'ASC_T_Rand'}". 

I can understand the meaning of the error but I cannot identify which part of the code needs to be modified. I tried different modifications but I cannot get rid of this error.

Please, if you could help me to identify the modification that I need to do in my code? I have attached the .py file to this email for your reference.

Looking forward to hearing from you.

Thank you so much. Kind regards.

Saptarshi
