-
class
xarray.core.rolling_exp.
RollingExp
(obj, windows, window_type='span')¶ Exponentially-weighted moving window object. Similar to EWM in pandas
- Parameters
windows (mapping of hashable to
int
) – A mapping from the name of the dimension to create the rolling exponential window along (e.g. time) to the size of the moving window.window_type (
{"span", "com", "halflife", "alpha"}
, default:"span"
) – The format of the previously supplied window. Each is a simple numerical transformation of the others. Described in detail: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.ewm.html
- Returns
RollingExp (
