Fast and Accurate Genome-Wide Association Test of Multiple Quantitative Traits

Table 3

Power of multitrait tests for continuous traits under significance level . The MAFs of SNP are 0.1 and 0.2 in the two populations, respectively. is the -DF omnibus Wald test; and are the 1-DF Wald tests assuming common or common scaled effect. are the corresponding GEE-based -DF omnibus test and 1-DF tests assuming a common effect or common scaled effect. is the standard error of and is the SNP coefficient, . The highest powered tests are bold-faced.
