SidakSD: Sidak-like (1987) step-down procedure

Description Usage Arguments Value Author(s) References Examples

Description

The Sidak-like (1987) step-down procedure is applied to pValues The Sidak-like step-down procedure is an improvement over the Holm's (1979) step-down procedure. The improvement is analogous to Sidak's correction over the original Bonferroni procedure. This Sidak-like step-down procedure assumes positive orthant dependent test statistics.

Usage

1
SidakSD(pValues, alpha, silent=FALSE)

Arguments

pValues

The used raw pValues.

alpha

The level at which the FWER shall be controlled.

silent

If true any output on the console will be suppressed.

Value

A list containing:

adjPValues

a numeric vector containing the adjusted pValues

rejected

a logical vector indicating which hypotheses are rejected

criticalValues

a numeric vector containing critical values used in the step-up-down test

errorControl

A Mutoss S4 class of type errorControl, containing the type of error controlled by the function and the level alpha.
