scipy.spatial.distance.russellrao(u, v)

Computes the Russell-Rao dissimilarity between two boolean n-vectors u and v, which is defined as

\frac{n - c_{TT}}

where c_{ij} is the number of occurrences of \mathtt{u[k]} = i and \mathtt{v[k]} = j for k < n.

Parameters :

u : ndarray

An n-dimensional vector.

v : ndarray

An n-dimensional vector.

Returns :

d : double

The Russell-Rao dissimilarity between vectors u and v.
