DFDR.p.adjust {MHTmult}

Adjusted P-Values for the Double FDR Procedure

Description

Given a list/data frame of grouped p-values, retruns adjusted p-values to make decisions

Usage

DFDR.p.adjust(pval, t, make.decision, alpha)

Arguments

pval

the structural p-values, the type should be "list".

t

the threshold selecting significant families.

make.decision

logical; if TRUE, then the output include the decision rules compared adjusted p-values with significant level \alpha.

alpha

significant level used to compare with adjusted p-values to make decisions, the default value is 0.05.

Value

A list of the adjusted p-values, a list of NULL means the family is not selected to do the test in the second stage.
