f.power: Power and sample size for the F distribution

In haplo.stats: Statistical Analysis of Haplotypes with Traits and Covariates when Linkage Phase is Ambiguous

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
