Figure 1 Bivariate normal probability represented by PACT when L=2 for one-sided tests (A) and two-sided tests (B). Elliptical lines represent the contours of a bivariate normal density function with positive correlation. Shaded area represents the space (extending to infinity) over which the probability PACT is measured.

Figure 4 A, Estimates of PACT and Pperm for 3,007 SNPs tested for disease association under three genetic models. B, Estimates of PACT and Pperm for 3,584 SNPs tested for association with 18 quantitative traits. Unblackened circles represent 3,575 SNPs genotyped for the candidate-gene study. Blackened circles represent nine simulated SNPs.
