Statistical functions (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):
Continuous distributions¶
Multivariate distributions¶
Discrete distributions¶
Statistical functions¶
Several of these functions have a similar version in scipy.stats.mstats which work for masked arrays.
Circular statistical functions¶
Contingency table functions¶
contingency.expected_freq (observed) |
Compute the expected frequencies from a contingency table. |
contingency.margins (a) |
Return a list of the marginal sums of the array a. |
Plot-tests¶
Masked statistics functions¶
Univariate and multivariate kernel density estimation (scipy.stats.kde
)¶
For many more stat related functions install the software R and the interface package rpy.
