power.oneway {FDRsamplesize2}

Compute power of one-way ANOVA

Description

Compute power of one-way ANOVA; Uses classical power formula for ANOVA; Assumes equal variance and sample size

Usage

power.oneway(n, alpha, theta, k = 2)

Arguments

n

per-group sample size (scalar)

alpha

p-value threshold (scalar)

theta

sum of ((group mean - overall mean)/stdev)^2 across all groups for each hypothesis test(vector)

k

the number of groups to be compared, default k=2

Details

For many applications, the null effect is zero for the parameter theta described above

Value

Vector of power estimates for test of equal means

Examples

theta=rep(c(2,0),c(100,900));
res = power.oneway(n = 50, alpha = 0.05, theta = theta, k = 2)
