Description Usage Arguments References
Return the variant set association test statistic and p-value. Aadapted from Maity et. al approach for rare variant set association test using weighted linear kernel.
1 2 |
Y |
pxn matrix, each row is one response, each column is one subject |
X.list |
a list where each item of list is a qxn matricx (parametric design matrix), where each row is one covariate (possiblly different for all items in Y), intercept must be included! |
Sigma |
covariance matrix of multivariate outcomes; estimate from data if NULL |
Gm |
genotype matrix with SNPs in column |
W |
variant weight; use Beta dist weight if NULL |
W.beta |
Beta distribution parameters for the variant weight. Default to Beta(1,25). |
n.sim |
number of simulation to obtain the null distribution of the test statistic; using analytical method if NULL |
