Figure 1

ROC curve. Power simulation of 11,010 SNPs, 1845 individuals. P-values are corrected via genomic control using the corresponding inflation factor from the simulation under H ₀. The abscissas are given in logarithmic scale. The upper plot compares the MCAT⁽²⁾ with the principal components approach. The lower plot shows the asymptotic test MCAT⁽¹⁾. The subscripts in the legend denote the employed structures: clusters c, groups (pairs) with cluster validation gc (pc) and groups (pairs) with vicinity validation gv (pv).
