GA.SSD.All: Genetic association tests for multiple regions/genes using...

In LGEWIS: Tests for Genetic Association/Gene-Environment Interaction in Longitudinal Studies

Description

Test the association between an quantitative outcome and multiple region/genes using SSD format files.

Usage

GA.SSD.All(SSD.INFO, result.prelim, Gsub.id=NULL, B=5000, ...)

Arguments

SSD.INFO	SSD format information file, output of function “Open_SSD". The sets are defined by this file.
result.prelim	Output of function "GA.prelim()".
Gsub.id	The subject id corresponding to the genotype matrix, an m dimensional vector. This is in order to match the phenotype and genotype matrix. The default is NULL, where the order is assumed to be matched with Y, X, E and time.
B	Number of Bootstrap replicates. The default is 5000.
...	Other options of the generalized score type test. Defined same as in function "GA.test()".

Details

Please see SKAT vignettes for using SSD files.

Value

results	Results of the set based analysis. First column contains the set ID; Second column (second and third columns when the MinP test is compared) contains the p-values; Last column contains the number of tested SNPs.
results.single	Results of the single variant analysis for all variants in the sets. First column contains the regions' names; Second column is the variants' names; Third column contains the minor allele frequencies; Last column contains the p.values.
