Twostage association testing procedure. In the first stage, phenotype
y
and genotype G
are each regressed on the model matrix
X
to obtain residuals. The phenotypic residuals are transformed
using rankNorm
. In the next stage, the INTtransformed
residuals are regressed on the genotypic residuals.
1 
y 
Numeric phenotype vector. 
G 
Obs by snp genotype matrix. 
X 
Model matrix of covariates and structure adjustments. Should include an intercept. Omit to perform marginal tests of association. 
k 
Offset applied during ranknormalization. See

simple 
Return the pvalues only? 
parallel 
Logical indicating whether to run in parallel. Must register parallel backend first. 
If simple=T
, returns a vector of pvalues, one for each column
of G
. If simple=F
, returns a numeric matrix, including the
Wald or Score statistic, its standard error, the Zscore, and the pvalue.
