From: Detecting gene-gene interactions using a permutation-based random forest method
Statistical epistasis network (SEN) and permuted random forest networks (PRFN). a shows the largest connected components from statistical epistasis network, which includes 39 SNPs. The largest connected components were divided into three clusters. Permuted Random Forest (pRF) was applied using the SNPs within each of the three clusters separately. b, c and d show the PRFNs built from each cluster. The width of the edges are in proportion to how strong the interactions exist, which are represented by the differences in error rates using our method. The cut-off for the SEN was based on entropy value of 0.013. PRFNs were built using same numbers of edges as in each cluster in SEN
