Calibrating the Performance of SNP Arrays for Whole-Genome Association Studies

Figure 3

Weighted estimates for statistical power by taking the weighted average of the power on HapMap causal SNPs (weight = 2.2/7.5) and that on NonHapMap causal SNPs (weight = 5.3/7.5).

(A) Kruskal-Wallis tests. (B) Spearman rank correlation tests. Further, we quantified the power of “direct genotyping,” where association tests were conducted on causal SNPs. This represents an upper bound on statistical power in WGAS.
