VTWOD: VT and WOD for RV Tests

Description

Include methods: T1, T5, WE, VT, and WOD.

Usage

VTWOD(x, y, polyphen.weight, flipPhenotype = 0, 
	npermutation = 1000, npermutation.max, min.nonsignificant.counts)

Arguments

x

Genotype matrix

y

Phenotype vector

Value

score

Scores of T1, T5, WE, VT, and WOD

nonsignificant.counts

pvalue.empirical

Empirical pvalue via permutation

pvalue.nominal

Theoretical pvalue, not available now.

total.permutation

Total permutation
