f.power {haplo.stats}R Documentation

Power and sample size for the F distribution

Description

Power and sample size for the F distribution given non-centrality, degrees of freedom, alpha, N (for f.power), and power (for f.sample.size)

Usage

f.power(n, nc, df1, alpha)
f.power.dif(n, nc, df1, alpha, power)
f.sample.size(nc, df1, alpha, power, lower=20, upper=10000)

Arguments

n sample size
nc non-centrality parameter
df1 degrees of freedom for numerator of f distribution
alpha type-I error
power desired power (for sample size)
lower lower limit for search space for sample size solution
upper upper limit for search space for sample size solution

Value

power, the difference in power from target power, and sample size, respectively for the three functions, assuming an F distribution for the test statistic
