Abstract: | A full bivariate generalization of the Anscombe-Tukey one degree of freedom for univariate non-additivity is presented, and is compared to other proposals. Higher dimensional extensions follow directly. In general, k(k+1)/2 degrees of freedom can be allocated to assessing non-additivity in k dimensions. Hence coordinate-wise additivity is necessary but not sufficient for multivariate additivity. |
