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).
