scipy.cluster.hierarchy.maxRstat

scipy.cluster.hierarchy.maxRstat(Z, R, i)

Returns the maximum statistic for each non-singleton cluster and its descendents.

Parameters :

Z : array_like

The hierarchical clustering encoded as a matrix. See linkage for more information.

R : array_like

The inconsistency matrix.

i : int

The column of R to use as the statistic.

Returns :

MR : ndarray

Calculates the maximum statistic for the i’th column of the inconsistency matrix R for each non-singleton cluster node. MR[j] is the maximum over R[Q(j)-n, i] where Q(j) the set of all node ids corresponding to nodes below and including j.
