Distribution of maximum correlations between false positives and true nonzeros after the presumptive
P − value
phase transition for chromosome 22. Histogram of the maximum correlation (maximum of the positive roots of the r
2 LD measure) between a false positive and true nonzero for chromosome 22, given s = 125, n = 5,000, and h
2 = 0.5 (red). Also shown is one realization from the null distribution, generated by drawing an equal number of “false positives” at random from chromosome 22 (white).
