Assisted specification¶
Example of the estimation of several versions of the model using assisted specification algorithm. The catalog of specifications is defined in Specification of a catalog of models . Compared to plot_b21multiple_models, the number fo specifications exceeds the maximum limit, so a heuristic is applied. See Bierlaire and Ortelli, 2023 for a detailed description of the use of the assisted specification algorithm.

Creation of the object capturing the assisted specification algorithm. Its constructor takes three arguments:
the biogeme object containing the specifications and the database,
an object defining the objectives to minimize. Here, we use three objectives: AIC, BIC and number of parameters.
the name of the file where the estimated are saved, and organized into a Pareto set.

biogeme_object=the_biogeme,
multi_objectives=aic_bic_dimension,

Unable to read file b22_multiple_models.pareto. Pareto set empty.
