class biogeme.expressions.draws.Draws(name, draw_type)

Bases: Elementary

Draws for Monte-Carlo integration

Parameters:

• name (str)

• draw_type (str)

deep_flat_copy()

Provides a copy of the expression. It is deep in the sense that it generates copies of the children. It is flat in the sense that any MultipleExpression is transformed into the currently selected expression. The flat part is irrelevant for this expression.

Return type:

Draws

expression_type = 6

recursive_construct_jax_function(numerically_safe)

Generates a function to be used by biogeme_jax. Must be overloaded by each expression :rtype: Callable[[Array, Array, Array, Array], array] :return: the function takes two parameters: the parameters, and one row of the database.

Parameters:

numerically_safe (bool)

Return type:

Callable[[Array, Array, Array, Array], array]

property safe_draw_id: int

Check the presence of the draw ID before its usage
