Robust Association Tests for the Replication of Genome-Wide Association Studies

Table 1

Type I error rates of three approaches—replication-based (REP) test, Fisher’s combination (), and linear combination of test ()—based on the CATT with an additive model (), , MAX3, MIN2, GMS, and GME. The disease prevalence , markers, cases, and controls are considered based on 20,000 simulations.
