Figure 5From: A robustness study of parametric and non-parametric tests in model-based multifactor dimensionality reduction for epistasis detection Scatter plot matrices of MB-MDR multiple testing corrected p -values for the causal SNP pair for a variety of a priori data transformations. Only MB-MDR results with Student’s t testing for associations are shown. The epistatic contribution to the trait variance is set to 10%. Legend: Different scenario’s of trait distribution are considered: normal traits and homogeneity (panel A); normal traits and heteroscedasticity (panel B); chi-squared distributed traits and homogeneity (panel C); chi-squared distributed traits and variance heterogeneity (panel D).Back to article page
