A survey about methods dedicated to epistasis detection

Front Genet
PMCID: 4564769
PMID: 26442103
DOI: 10.3389/fgene.2015.00285

[…] several independent SNPs additively contributing to the phenotype. As a result, random forests are lacking clear interpretation.More recently, another tree assembling software program was developed: GWGGI (Wei and Lu, ). It differs from the previous methods in two points. First, it uses a tree-growing algorithm which is more computationally efficient (Lu et al., ): the standard variable selection […]


Analysis pipeline for the epistasis search – statistical versus biological filtering

Front Genet
PMCID: 4012196
PMID: 24817878
DOI: 10.3389/fgene.2014.00106

[…] n. They use a multi-locus Mann–Whitney statistic to evaluate the joint association of a SNP combination. Using a computationally efficient forward selection algorithm makes these methods feasible for genome-wide gene–gene interaction analyses. Nevertheless, they require at least one SNP in the combination to have a significant marginal association. The non-parametric approaches do not suffer from […]
