class biogeme.expressions.random_variable.RandomVariable(name)

Bases: Elementary

Random variable for numerical integration

Parameters:

name (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:

RandomVariable

expression_type = 5

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_rv_id: int

Check the presence of the ID before using it
