mt.reject: Identity and number of rejected hypotheses

Description

This function returns the identity and number of rejected hypotheses for several multiple testing procedures and different nominal Type I error rates.

Usage

mt.reject(adjp, alpha)

Arguments

adjp

A matrix of adjusted p-values, with rows corresponding to hypotheses and columns to multiple testing procedures. This matrix could be obtained from the function mt.rawp2adjp .

alpha

A vector of nominal Type I error rates.

Value

A list with components

r

A matrix containing the number of rejected hypotheses for several multiple testing procedures and different nominal Type I error rates. Rows correspond to Type I error rates and columns to multiple testing procedures.

which

A matrix of indicators for the rejection of individual hypotheses by different multiple testing procedures for a nominal Type I error rate alpha[1]. Rows correspond to hypotheses and columns to multiple testing procedures.

Examples

# Gene expression data from Golub et al. (1999)
# To reduce computation time and for illustrative purposes, we condider only
# the first 100 genes and use the default of B=10,000 permutations.
# In general, one would need a much larger number of permutations
# for microarray data.
