scipy.spatial.distance.correlation#

scipy.spatial.distance.correlation(u, v, w=None, centered=True)[source]#

Compute the correlation distance between two 1-D arrays.

The correlation distance between u and v, is defined as

\[1 - \frac{(u - \bar{u}) \cdot (v - \bar{v})} {{\|(u - \bar{u})\|}_2 {\|(v - \bar{v})\|}_2}\]

where \(\bar{u}\) is the mean of the elements of u and \(x \cdot y\) is the dot product of \(x\) and \(y\).

Parameters

u(N,) array_like: Input array.
v(N,) array_like: Input array.
w(N,) array_like, optional: The weights for each value in u and v. Default is None, which gives each value a weight of 1.0
centeredbool, optional: If True, u and v will be centered. Default is True.

Returns
