Hello,

We are trying to create the Auto Ownership Choice Model. When we have the independent variables from the 'household' dataset only, we obtain a singular matrix. It seems that it's not enough to be limited to the household attributes. We are trying to use the interaction variables from the 'household_x_gridcell' dataset, but we get the error:

"ValueError: different dataset names for variable and dataset or a component".

In the auto_ownership_choice_model_configuration_creator we specified: agent_set = Str('household') and choice_attribute_name = Str('cars'), where 'cars' is an attribute from the 'household' dataset. We also have choice_set = ListInt([0,1,2]). So we get the interaction dataset 'household_x_choice' and we seem to be limited to the variables that are part of that dataset.

Is it possible to use variables from 'household_x_gridcell' in this case where there is already an interaction with another dataset which is choice?

Thank you,

Mark
