Figure 2From: Comparison of affected sibling-pair linkage methods to identify gene × gene interaction in GAW15 simulated dataMean interaction test on chromosome 16. The percent of significant results (at α = 0.05) is plotted against the centimorgan (cM) location. Solid circles represent the model with no covariate; plus signs indicate the joint test of π and β; and the diamonds represent the model with the interaction term (β) only.Back to article page
