pwr.omegasq: Power calculations for Omega Squared.

Description

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

Usage

pwr.omegasq(
  k = NULL,
  n = NULL,
  omegasq = NULL,
  sig.level = 0.05,
  power = NULL,
  digits = 4
)
# S3 method for pwr.omegasq
print(x, digits = x$digits, ...)

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

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).

x

The object to print.

...

Additional arguments are ignored.
