scipy.cluster.hierarchy.
average
(y)[source]¶ Perform average/UPGMA linkage on a condensed distance matrix.
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
linkage
for more information on its structure.
See also
