Compute the inconsistency coefficient for each link of a hierarchical cluster tree.
Given a hierarchical cluster tree Z generated by the linkage
function, inconsistent computes the inconsistency coefficient for each
link of the tree, using all the links down to the d-th level below that
link.
The default depth d is 2, which means that only two levels are considered: the level of the computed link and the level below that.
Each row of Y corresponds to the row of same index of Z. The columns of Y are respectively: the mean of the heights of the links used for the calculation, the standard deviation of the heights of those links, the number of links used, the inconsistency coefficient.
