dcor: distance correlation and energy statistics in Python.
E-statistics are functions of distances between statistical observations in metric spaces.
Distance covariance and distance correlation are dependency measures between random vectors introduced in [SRB07]_ with a simple E-statistic estimator.
This package offers functions for calculating several E-statistics such as:
It also provides tests based on these E-statistics:
dcor is on PyPi and can be installed using :code:pip
:
.. code::
pip install dcor
It is also available for :code:conda
using the :code:conda-forge
channel:
.. code::
conda install -c conda-forge dcor
Previous versions of the package were in the :code:vnmabus
channel. This
channel will not be updated with new releases, and users are recommended to
use the :code:conda-forge
channel.
dcor is available in Python 3.8 or above in all operating systems. The package dcor depends on the following libraries:
