pandas.Series.corr — pandas 0.25.3 documentation (original) (raw)

Series. corr(self, other, method='pearson', min_periods=None)[source]¶

Compute correlation with other Series, excluding missing values.

Parameters:	other : Series Series with which to compute the correlation. method : {‘pearson’, ‘kendall’, ‘spearman’} or callable pearson : standard correlation coefficient kendall : Kendall Tau correlation coefficient spearman : Spearman rank correlation callable: callable with input two 1d ndarrays and returning a float. Note that the returned matrix from corr will have 1 along the diagonals and will be symmetric regardless of the callable’s behavior .. versionadded:: 0.24.0 min_periods : int, optional Minimum number of observations needed to have a valid result.
Returns:	float Correlation with other.

Parameters:

other : Series Series with which to compute the correlation. method : {‘pearson’, ‘kendall’, ‘spearman’} or callable pearson : standard correlation coefficient kendall : Kendall Tau correlation coefficient spearman : Spearman rank correlation callable: callable with input two 1d ndarrays and returning a float. Note that the returned matrix from corr will have 1 along the diagonals and will be symmetric regardless of the callable’s behavior .. versionadded:: 0.24.0 min_periods : int, optional Minimum number of observations needed to have a valid result.

Returns:

float Correlation with other.
