ORMDR (version 1.3-2)

mdr.c: 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)
