get.scores.pvalues: function to compute scores and p-values

Description Usage Arguments Value Author(s) See Also Examples

View source: R/get.scores.pvalues.R

Description

For each tested SNP and each parameter in the model, computes scores by summing family scores over all families and computes the corresponding p-values. P-values of global and joint tests are also computed.

Usage

1
get.scores.pvalues(test, joint.tests)

Arguments

test

object returned by fat2Lpoly.withinR.

joint.tests

list of vectors of numbers between 1 and the total number of parameters in the design function. Each vector gives parameter indices to test the corresponding parameters jointly.

Value

data frame of p-values for all the tested SNPs, for the global test (all parameters tested jointly), the individual tests and other joint tests specified by the argument joint.tests. The p-values are obtained from scores summed over all families. These scores of individual tests are also included in this data frame.
