Compared to EIGENSTRAT, Coal-Map has comparable or better power and false positive rate on model conditions involving neutral gene flow (hybridization frequency γ=0.5). 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 area-under-ROC-curve (AUROC) of 0.938 and 0.870, respectively. b Results are shown for the two-causal-loci model condition. Coal-Map has an AUROC of 0.898 and EIGENSTRAT has an AUROC of 0.860. c Results are shown for the all-causal-loci model condition, where Coal-Map and EIGENSTRAT have AUROC of 0.837 and 0.827, respectively
