Figure 4From: Variance heterogeneity analysis for detection of potentially interacting genetic loci: method and its limitationsDependence of power to detect interaction (left plot) with threshold corresponding to α = 0.05 and non-centrality parameter (right plot) on effect of interaction. Thin curve on each subplot corresponds to direct test, bold curve corresponds to upper limit of variance homogeneity test. Each subplot corresponds to different frequency of interacting allele (A - 0.05, B - 0.4, C - 0.6, D - 0.95).Back to article page
