class biogeme.expressions.integrate.IntegrateNormal(child, name, number_of_quadrature_points=30)

Bases: UnaryOperator

Numerical integration

Parameters:

• child (ExpressionOrNumeric)

• name (str)

• number_of_quadrature_points (int)

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:

IntegrateNormal

recursive_construct_jax_function(numerically_safe)

Generates recursively a function to be used by PyMc. Must be overloaded by each expression :rtype: Callable[[Array, Array, Array, Array], array] :return: the expression in TensorVariable format, suitable for PyMc

Parameters:

numerically_safe (bool)

Return type:

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

property safe_rv_id: int

Check the presence of the random variable ID before its usage

set_specific_id(name, specific_id, the_type)

The elementary IDs identify the position of each element in the corresponding datab

Parameters:

the_type (TypeOfElementaryExpression)
