From: A powerful score-based test statistic for detecting gene-gene co-association
The power of the seven methods under different co-association levels with two main effects (β 1 = log(1.3), β 2 = log(1.5)). Note: figure (a) for Type I co-association with different interaction effects; figure (b) for Type II co-association with different causal SNP pairs; figure (c) for Type III co-association given fixed correlation 0.3 and different interaction effects; figure (d) for Type III co-association given fixed interaction effect β 3 = log(1.3) and different causal SNP pairs
