Probability distributions
=========================

The :mod:`sktime.distributions` module contains
probability distributions which combine a ``pandas.DataFrame``-like API
with a ``scikit-base`` compatible object interface.

All distributions in ``skpro`` can be listed using the ``skpro.registry.all_objects`` utility,
using ``object_types="distribution"``, optionally filtered by tags.
Valid tags can be listed using ``sktime.registry.all_tags``.
