cudf.Series.cov

Series.cov(other, min_periods=None, ddof: int | None = None)

Compute covariance with Series, excluding missing values.

Parameters:

otherSeries

Series with which to compute the covariance.

Returns:

float

Covariance between Series and other normalized by N-1 (unbiased estimator).

Examples

>>> import cudf
>>> ser1 = cudf.Series([0.9, 0.13, 0.62])
>>> ser2 = cudf.Series([0.12, 0.26, 0.51])
>>> ser1.cov(ser2)
-0.015750000000000004
