Subplots (A) and (B) are computed under conditions 1 and 2, respectively (see text). The red line represents a chi square distribution with 4 degrees of freedom.|

The color represents the number of tests on a logarithmic scale in each point determined by the P-values obtained by both methods for each data set for the 48 basic epistatic models. Although LRIT is marginally more powerful, it is clear that the performance of both methods is very similar.|
|gepi21665-sup-0003-FigureS3.doc||226K||Figure S3 Probability-probability density plot for the case-only χ2 (x axis) and the case-control 2χ2 method (y axis). The color represents the number of tests on a logarithmic scale in each point determined by the P-values obtained by both methods for each data set for the 48 basic epistatic models. Different prevalences (0.01, 0.05, 0.1, 0.15, 0.2) are colored with different gradient colors. Higher prevalences present higher slope. The simulations are done with 500 cases and 500, 1000, and 1500 controls for subplots (A), (B), and (C), respectively.|
