In daewr: Design and Analysis of Experiments with R

F-Distribution Power Calculation

Description

Calculates the power for a two-way ANOVA

Usage

Fpower2(alpha,nlev,nreps,Delta,sigma)

Arguments

alpha	input - significance level of the F-test.
nlev	input - vector of length two containing the number of levels of the factors.
nreps	input - the the number of replicates in each combination of factor levels.
Delta	input - the size of a practical difference in two marginal factor level means.
sigma	input - the standard deviation of the experimental error.

Value

probability of exceeding fcrit(alpha, nu1,nu2) with the non-central F-distribution with nu1 and nu2 degrees of freedom and noncentrality parameter nc
