Window

Rolling objects are returned by .rolling calls: pyspark.pandas.DataFrame.rolling(), pyspark.pandas.Series.rolling(), etc.

Expanding objects are returned by .expanding calls: pyspark.pandas.DataFrame.expanding(), pyspark.pandas.Series.expanding(), etc.

ExponentialMoving objects are returned by .ewm calls: pyspark.pandas.DataFrame.ewm(), pyspark.pandas.Series.ewm(), etc.
