mutoss (version 0.1-4)

hommel: Hommel's (1988) step-up-procedure

Description

Hommel's step-up-procedure.

Usage

hommel(pValues, alpha, silent=FALSE)

Arguments

pValues

pValues to be used. They need a independent structure.

alpha

The level at which the FWER should be controlled

silent

Logical. 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.

Details

The method is applied to p-values. It controls the FWER in the strong sense when the hypothesis tests are independent or when they are non-negatively associated.

The method base upon the closure principle to assure the FWER alpha and the critical Values of this procedure are given by alpha/n, alpha/(n-1), ..., alpha/2, alpha/1.

Examples

pval <- c(runif(50), runif(50, 0, 0.01))
result 	<- hommel(pval, 0.05)
result 	<- hommel(pval, 0.05, silent = TRUE)
