Description

Perform a power analysis, with plots for null and alternative distributions

Usage

power1(
  mu0 = 50,
  mu1 = 50,
  sd = 10,
  n = 100,
  alpha = 0.05,
  alt.hyp = "mu1<>mu0",
  show.values = FALSE,
  show.means = FALSE
)

Arguments

mu0	A value for the mean under the null hypothesis
mu1	A value for the mean under the alternative hypothesis
sd	A positive value for the standard deviation for the population (null)
n	A value for the sample size
alpha	A value between .005 and .1 for the Type I error rate
alt.hyp	One of: "mu1<>mu0", "mu1<mu0", or "mu1>mu0"
show.values	Select whether Type I, II, and Power are displayed in plot.
show.means	Whether to plot means for Ho and Ha

Value

res Summary, included Type I error (alpha), Type II error (beta), and Power
