the partition includes members of both groups then the covariance will be larger than zero. However, if the premise regarding dimensionality is true, no substantial change in covariance of Y and Z is expected when moving the cut point along the range of X. Graphical inspection of plotting the covariance as a function of splitting on X is used to support a decision in favor of either dimensionality or taxonicity.
