pandas.core.window.ewm.ExponentialMovingWindow.corr¶

ExponentialMovingWindow.corr(other=None, pairwise=None, **kwargs)[source]¶

Calculate the ewm (exponential weighted moment) sample correlation.

Parameters

otherSeries or DataFrame, optional: If not supplied then will default to self and produce pairwise output.
pairwisebool, default None: If False then only matching columns between self and other will be used and the output will be a DataFrame. If True then all pairwise combinations will be calculated and the output will be a MultiIndex DataFrame in the case of DataFrame inputs. In the case of missing elements, only complete pairwise observations will be used.
**kwargs: For NumPy compatibility and will not have an effect on the result.

Returns

Series or DataFrame: Return type is the same as the original object with np.float64 dtype.
