Figure S1. Power at 5.10–8 significance level to detect association signal when analysing 2000 individuals function of the amplitude of interaction effect. Power is presented for the test of marginal linear effect (MARG), the D_{c} test (DC), the D_{u} test (DU), the Levene test of variances (LEV), and the joint test while using either the true exposure or exposures correlated with the true exposure at the 0.7, 0.5 and 0.3 level (joint_1.0, joint_0.7, joint_0.5 and joint_0.3 respectively). Power is presented when the main and interaction effects of the SNP are in the same direction (A,B and C), and when main effect and interaction effects are in opposite directions (D, E and F). Figure S2. Power at 5.10–8 significance level to detect association signal when analysing 2000 individuals. Power is presented for the test of marginal linear effect (MARG), the D_{c} test (DC), the D_{u} test (DU), the Levene test of variance (LEV), and the joint test while using either the true exposure or exposures correlated with the true exposure at the 0.7, 0.5 and 0.3 level (joint_1.0, joint_0.7, joint_0.5 and joint_0.3 respectively). Power is presented in the presence of two interaction effects in the same direction (A), and in the presence of a two interaction in opposite direction having either different amplitude (B) or the same amplitude (C). Figure S3. QQplot of the D_{c} test (DC), D_{u} test (DU), the Levene's test of variance (LEV), linear regression (MARG). Figure S4. Power at 0.05 significance level of the D_{c} test (DC), D_{u} test (DU), the Levene's test of variance (LEV), linear regression (MARG), the two-sample Kolmogorov-Smirnov test (KS), the two-sample Cramèr Von-Mises test (CRAMER), the two-sample Wilcoxon rank sum test (RANK), the two-sample Student's t test (t) and the generalized version of the two later tests (RANK.gen and t.gen) as described by O'Brien[O'Brien 1988]. Power has been computed among 10,000 simulations, when analyzing 300 individuals for the test of a biallelic genetic variant in the presence of one interaction effect only. The interaction effect and exposure frequency were set so that the marginal effect size is fixed at 0.2. Figure S5. Power at 0.05 significance level of the D_{c} test (DC), D_{u} test (DU), the Levene's test of variance (LEV), linear regression (MARG), the two-sample Kolmogorov-Smirnov test (KS), the two-sample Wilcoxon rank sum test (RANK), the two-sample Student's t test (t) and the generalized version of the two later tests (RANK.gen and t.gen) as described by O'Brien [O'Brien 1988]. Power has been computed among 10,000 simulations, when analyzing 2000 individuals for the test of a biallelic genetic variant in the presence of one interaction effect only. The interaction effect and exposure frequency were set so that the marginal effect size is fixed at 0.1. The Cramèr Von-Mises test was not applied in this simulation because the sample size was two large to be handled by the algorithm we used [Xiao et al., 2006]. Figure S6.
