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.
