Power curve for partition ${\mathcal{S}}^{\prime }=\left\{R,Y\right\}$. A total of 3000 divergence matrices were generated by Monte Carlo simulation for each triplet of points, corresponding to the three test statistics, and 500 parametric bootstraps were used during the calculation of P-values for the η index. The same π-vector (i.e., π^T = (0.1, 0.2, 0.3, 0.4)) was used for every triplet of points whereas the values in the s-vector were allowed to vary slightly for each point.
