scipy.cluster.hierarchy.maxRstat¶

scipy.cluster.hierarchy.maxRstat(Z, R, i)[source]¶

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

Parameters:

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`.

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.
