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.
Value
A matrix of adjusted p-values.

Examples
pvalues <- matrix(c(0.01,0.005,0.015,0.022, 0.02,0.015,0.010,0.023),
nrow=2, ncol=4, byrow=TRUE)
ftrunc(pvalues, "hochberg")
#> [,1] [,2] [,3] [,4]
#> [1,] 0.022 0.020 0.022 0.022
#> [2,] 0.023 0.023 0.023 0.023
