Figure 3

Empirical power of ΛR and ΛG obtained with α1 = β2 = log(2) under Type A interaction (Column 1) and Type D interaction (Column 2) under different levels of correlations between the risk factors (Rows 1, 2, and 3). Empirical power under compositional epistasis is shown in Column 3. In each panel, the horizontal axis represents the magnitude of the interaction parameter γ11 used in the simulations. The black lines denote the empirical power of ΛR and the red lines are the empirical power of ΛG.
