Compared to EIGENSTRAT, Coal-Map has comparable or better power and false positive rate on model conditions involving adaptive gene flow (hybridization frequency γ=0.5 and selection coefficient s=0.56). True positive rate and false positive rate are shown for both methods using receiver operating characteristic (ROC) curves. a Results are shown for the model condition where causal SNPs are drawn from a single locus. Coal-Map and EIGENSTRAT have AUROC of 0.947 and 0.889, respectively. b Results are shown for the two-causal-loci model condition. Coal-Map has an AUROC of 0.897 and EIGENSTRAT has an AUROC of 0.859. c Results are shown for the all-causal-loci model condition, where Coal-Map and EIGENSTRAT have AUROC of 0.845 and 0.816, respectively
