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

Computes the Sokal-Sneath dissimilarity between two boolean vectors u and v,

     {c_{TT} + R}

where c_{ij} is the number of occurrences of \mathtt{u[k]} = i and \mathtt{v[k]} = j for k < n and R = 2(c_{TF} + c_{FT}).

Parameters :

u : ndarray

An n-dimensional vector.

v : ndarray

An n-dimensional vector.

Returns :

d : double

The Sokal-Sneath dissimilarity between vectors u and v.
