Table 1. Powers obtained by three epistasis detection methods for three-way, four-way and five-way interactions.

Interaction order	CSE	MDR	BEAM
Three-way	69	45	48
Four-way	47	40	35
Five-way	18	12	31

Abbreviations: BEAM, Bayesian epistasis association mapping; CSE, cuckoo search epistasis; MDR, multifactorial dimensionality reduction; SNP, single-nucleotide polymorphism.

Power is estimated as the proportion of the 100 replicate data sets for which the method ranks the functional SNPs as the top three, four or five SNPs.
