Description

power_ftest performs the power calculation for the f-test comparing means of k > 2 independent samples. The method used here is based on the page 29 in [1].

Usage

power_ftest(mu_A, sd, n.groups, n_per_group, alpha)

Arguments

mu_A	Vector μ_A of expected means on the alternative.
sd	Standard deviation sigma.
n.groups	Number of Groups k.
n_per_group	Sample size per group.
alpha	Significance level α.

Value

n_ftest returns the power.

Examples

power_ftest(mu_A = c(1, 2, 3), sd = 20, n.groups = 3, n_per_group = 70, alpha = .025)
