MDR : Multifactor Dimensionality Reduction

Description

MDR method classifies the combination of multilocus tgenotypes into high-risk and low-risk groups based on a simple comparison of the ratios of the number of cases and controls.

Usage

mdr.c(dataset,colresp,cs,combi,cv.fold=10,randomize=TRUE)

Arguments

dataset SNP data set with class variable
colresp location of class variable in dataset
cs how to code "case" class
combi number of genes for combination
cv.fold number of fold in cross validation
randomize logical. If 'TRUE' (the default) the cross validation sets are randomized

Value

min.comb combination with minimum error rate in each cross validation
train.erate training error
test.erate test error
data dataset
best.combi best combination

Examples

data(sample.dat)
mdr.c(sample.dat, colresp=21, cs=1, combi=2, cv.fold = 10)
