Statistical functions (:mod:`scipy.stats`)
|
||||
==========================================
|
||||
|

.. currentmodule:: scipy.stats
|
||||
|
||||
This module contains a large number of probability distributions as
|
||||
well as a growing library of statistical functions.
|
||||
|
||||
Each univariate distribution is an instance of a subclass of `rv_continuous`
|
||||
(`rv_discrete` for discrete distributions):
