Description

Computes power of t-test for one-dimensional contrast matrices

Usage

contrast1D(
  object,
  L,
  method = c("Satterthwaite"),
  sig.level = 0.05,
  alternative = c("two.sided", "one.sided"),
  strict = TRUE
)

Arguments

object	design object
L	contrast vector
method	DF approximation method, only "Satterthwaite" available currently
sig.level	significance level, default 0.05
alternative	one- or two-sided test
strict	whether or not use strict interpretation in two-sided case

Value

A data frame with columns for effect size, degrees of freedom, significance level, power, and test type.
