confIntOmegaSq

Confidence intervals for Omega Squared

This function used the MBESS function conf.limits.ncf and convert.ncf.to.omegasq to compute the point estimate and confidence interval for Omega Squared.

Keywords
bivar
Usage
confIntOmegaSq(var1, var2, conf.level = 0.95)
Arguments
var1, var2
The two variables: one should be a factor (or will be made a factor), the other should have at least interval level of measurement. If none of the variables is a factor, the function will look for the variable with the least unique values and change it into a factor.
conf.level
Level of confidence for the confidence interval.
Value

A confIntOmegaSq object is returned, with as elements:

Note

Formula 16 in Steiger (2004) is used for the conversion in convert.ncf.to.omegasq.
