Figure 2From: Gene-environment interaction tests for family studies with quantitative phenotypes: A review and extension to longitudinal measures(a). Empirical power results for the main genetic effect assessment comparing different methods under the assumption of a stratified population. Simulations are based on the sample size as indicated in the plot and the additive genetic model. (b).
