scipy.cluster.hierarchy.weighted(y)

Performs weighted/WPGMA linkage on the condensed distance matrix y. See linkage for more information on the return structure and algorithm.

Parameters :

y : ndarray

The upper triangular of the distance matrix. The result of pdist is returned in this form.

Returns :

Z : ndarray

A linkage matrix containing the hierarchical clustering. See the linkage function documentation for more information on its structure.
