scipy.spatial.distance.yule(u, v)[source]ΒΆ

Computes the Yule dissimilarity between two boolean 1-D arrays.

The Yule dissimilarity is defined as

\[\frac{R}{c_{TT} * c_{FF} + \frac{R}{2}}\]

where \(c_{ij}\) is the number of occurrences of \(\mathtt{u[k]} = i\) and \(\mathtt{v[k]} = j\) for \(k < n\) and \(R = 2.0 * c_{TF} * c_{FT}\).

Parameters:

u : (N,) array_like, bool

Input array.

v : (N,) array_like, bool

Input array.

Returns:

yule : double

The Yule dissimilarity between vectors u and v.
