Cumulative distribution of 500 random SNP networks. Cumulative distribution of 500 random SNP networks. Each of these 500 random networks maintained the same size with our selected SNP network (49 SNPs). SNPs were selected randomly, calculated all pairwise SNP-SNP interactions using PLINK, got the average P-value of all pairs. This cumulative distribution is a statistics of these 500 random networks with X axis is the average P-value within this network and Y axis is the cumulative probability that within a particular X threshold.
