A unified model based MDR framework for detecting gene-gene interaction


A two-step unified model based MDR approach (UM-MDR), in which, the significance of a multi-locus model, even a high-order model, can be easily obtained through a regression framework, and a semiparametric correction procedure is designed to control type I error rates


  • Download the package umMAD_0.1.tar.gz from this respository
  • To install, in R:
install.packages("path/umMDR_0.1.tar.gz", repos = NULL, type = "source")


umMDR(snp.all, phe, K = 2, cova = NULL, classm = "mean",
adj.main = "FALSE", nperm = 5)


snps <- matrix(rbinom(100 * 5, 1, 0.2), nrow = 100)  ## generate 5 snps
phe <- rnorm(100)  ## generate phenotype
umMDR(snps, phe, 2)
