power: Power Functions

In alitvak3/a3personal: My personal functions

Description

These functions create a tibble showing the power at different true means.

Usage

power_func.z(
  mus,
  mu.0,
  sd,
  n,
  conf.level = 0.95,
  alternative = c("two.sided", "less", "greater")
)

power_func.t(
  mus,
  mu.0,
  sd,
  n,
  conf.level = 0.95,
  samples = c(1, 2),
  alternative = c("two.sided", "less", "greater")
)

Arguments

mus	a list or vector of true means or differences to be tested
mu.0	the hypothesized mean or difference
sd	standard deviation
n	number of observations
alternative	"two.sided", "less", or "greater", abbreviations accepted
samples	number of samples (1 or 2)

Functions

• power_func.z: creates a power function table based on the z method

• power_func.t: creates a power function table based on the t method
