Power Plots. Results of the power simulations for the four-taxon hybrid species network in Fig. 1. Plots (a), (b), (c), and (d) correspond to data simulated for the “short” branch length setting, and plots (e), (f), (g), and (h) correspond to data simulated for the “long” branch length settings. Plots (a) and (e) give results for the test based on \(\frac {f_{1}}{f_{2}}\); plots (b) and (f) give results for the test based \(\frac {f_{3}}{f_{4}}\); plots (c) and (g) give results for the test based on \(\frac {f_{1}+f_{3}}{f_{2}+f_{4}}\); and plots (d) and (h) give results for the ABBA-BABA test
