Figure 3From: On the potential of models for location and scale for genome-wide DNA methylation dataSimulation study: Observed type I error rates of hypothesis tests for covariate effects. Observed type I error is plotted against the effect size that the same covariate (BMI) had on the other distribution parameter. Simulation results are shown for beta distributed (A, B) and for real-data distributed methylation values (C, D). Model abbreviations are explained in Table 1.Back to article page
