pwr.omegasq {ufs} | R Documentation |
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.
pwr.omegasq( k = NULL, n = NULL, omegasq = NULL, sig.level = 0.05, power = NULL, digits = 4 ) ## S3 method for class 'pwr.omegasq' print(x, digits = x$digits, ...)
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. |
This function was written to work similarly to the power functions in the
pwr
package.
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 |
