====== Window

.. note:: For an overview, see :ref:window.

:class:pandas.api.typing.Rolling instances are returned by .rolling calls: :func:pandas.DataFrame.rolling and :func:pandas.Series.rolling. :class:pandas.api.typing.Expanding instances are returned by .expanding calls: :func:pandas.DataFrame.expanding and :func:pandas.Series.expanding. :class:pandas.api.typing.ExponentialMovingWindow instances are returned by .ewm calls: :func:pandas.DataFrame.ewm and :func:pandas.Series.ewm.
