Power comparison for different dimension-reduction tests when there is moderate correlation ( ρ ≈0 . 25) in gene. Power comparison between the Eigen-based test (red, dashed line) and Gauderman’s method (solid, black line underneath line referring to the Eigen test), 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 high LD (light blue, dashed line).
