scipy.spatial.distance.kulsinski

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

Computes the Kulsinski dissimilarity between two boolean n-vectors

u and v, which is defined as

rac{c_{TF} + c_{FT} - c_{TT} + n}

{c_{FT} + c_{TF} + n}

where is the number of occurrences of and for .

Parameters :

u : ndarray

An -dimensional vector.

v : ndarray

An -dimensional vector.

Returns :

d : double

The Kulsinski distance between vectors u and v.
