Figure 7

Power comparison for different dimension-reduction tests when there is no correlation in gene. Power comparison between the Eigen-based test (red, dashed line) and Gauderman’s method (solid, black line), along with a direct test of the causal SNPs (Wald and Score test lines are purple and blue, dashed, on top of one another) and tagging SNP under no LD (light blue, dashed line).
