The matrix of correlations (positive roots of the
LD measure) among false positives and true nonzeros after the presumptive
P − value
phase transition for chromosome 22 (
s = 125,
n = 5, 000, and
2 = 0.5
). SNP indices begin at the top left corner. The upper-left quadrant contains the correlations among false positives and the lower-right quadrant contains the correlations among the true nonzeros. Each element in the upper-right (lower-left) quadrant represents a correlation between a false positive and a true nonzero. Within both the false positive and the true nonzero sets, the markers are arranged in order of chromosomal map position.
