Dataset.rolling(dim=None, min_periods=None, center=False, **window_kwargs)[source]#

Rolling window object for Datasets.

  • dim (dict, optional) – Mapping from the dimension name to create the rolling iterator along (e.g. time) to its moving window size.

  • min_periods (int or None, default: None) – Minimum number of observations in window required to have a value (otherwise result is NA). The default, None, is equivalent to setting min_periods equal to the size of the window.

  • center (bool or Mapping to int, default: False) – Set the labels at the center of the window.

  • **window_kwargs (optional) – The keyword arguments form of dim. One of dim or window_kwargs must be provided.
