Returns the maximum statistic for each non-singleton cluster and
Z : ndarray
The hierarchical clustering encoded as a matrix. See
linkage for more information.
R : ndarray
The inconsistency matrix.
i : int
The column of R to use as the statistic.
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.
