Adjusted p-values for Holm, Hochberg, and Hommel procedures

Description

Obtains the adjusted p-values for possibly truncated Holm, Hochberg, and Hommel procedures.

Usage

ftrunc(p, test = "hommel", gamma = 1)

Arguments

p

The raw p-values for elementary hypotheses.

test

The test to use, e.g., "holm", "hochberg", or "hommel" (default).

gamma

The value of the truncation parameter. Defaults to 1 for the regular Holm, Hochberg, or Hommel procedure.
