`scipy.stats._distribution_infrastructure:_Parameterization`

source: /scipy/stats/_distribution_infrastructure.py :784

Signature

class _Parameterization ( * parameters )

Members

Summary

Represents a parameterization of a distribution.

Extended Summary

Distributions can have multiple parameterizations. A _Parameterization object is responsible for recording the parameters used by the parameterization, checking whether keyword arguments passed to the distribution match the parameterization, and performing input validation of the numerical values of these parameters.

Attributes

parameters : dict: String names (of keyword arguments) and the corresponding _Parameters.

Methods

__len__(): Returns the number of parameters in the parameterization.
__str__(): Returns a string representation of the parameterization.
copy: Returns a copy of the parameterization. This is needed for transformed distributions that add parameters to the parameterization.
matches(parameters): Checks whether the keyword arguments match the parameterization.
validation(parameter_values): Input validation / standardization of parameterization. Validates the numerical values of all parameters.
draw(sizes, rng, proportions): Draw random values of all parameters of the parameterization for use in testing.
