Power comparison in scenarios B and C. Selected tests are considered for power comparison in scenarios B and C, where all causal rare variants have the same genetic effect on the trait. Scenario B is the case that only rare variants affect the traits, while Scenario C is the case that both common and rare variants affect the traits. RSCsum represents selective Rsum. RSCind represents selective Rind. BwSum represents weighted sum test. BaSSUwOrd represents ordered adaptive sum test with test statistics of SSUw. BwSC represents weighted selectively collapsing test sensitive to the direction.
