# 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`.
