Empirical type I error rate and power for three real SNP data sets and synthetic phenotypes with 10 causal SNPs.
Each point represents the average type I error rate or power across multiple synthetic phenotypes (400 for Finnish and AVS and 4,000 for Mouse). In the Finnish power plot, methods that include select have greater power than those that do not.
