pwr.omegasq

This function uses pwr.anova.test from the pwr package in combination with convert.cohensf.to.omegasq and convert.omegasq.to.cohensf to provide power analyses for Omega Squared.

Keywords
htest
Usage
pwr.omegasq(k = NULL, n = NULL, omegasq = NULL,
            sig.level = 0.05, power = NULL, digits = 4)
Arguments
k
The number of groups.
n
The sample size.
omegasq
The Omega Squared value.
sig.level
The significance level (alpha).
power
The power.
digits
The number of digits desired in the output (4, the default, is quite high; but omega squared value tend to be quite low).
Details

This function was written to work similarly to the power functions in the pwr package.

Value

An power.htest.ufs object that contains a number of input and output values, most notably:

power
The (specified or computed) power
n
The (specified or computed) sample size in each group
sig.level
The (specified or computed) significance level (alpha)
sig.level
The (specified or computed) Omega Squared value
cohensf
The computed value for the Cohen's f effect size measure
