I'm looking for articles that describe methods of how to calculate CIs for the omega-squared effect size from an one-way ANOVA. The closest I've come is Finch & French (2011) A Comparison of Methods for Estimating Confidence Intervals for Omega-Squared Effect Size link, but they don't present any formulas.

I'd also welcome any links to an R implementation of either analytical estimates or bootstrap CIs.

Thanks for any help on this matter!

    $\begingroup$ At first blush, bootstrapping should be an easy way to do get such a CI. Do you need sample code to figure out how to do this in R? $\endgroup$ – gung Jul 14 '12 at 18:18
  • $\begingroup$ @gung Thanks, I have a pretty good idea how to bootstrap such a CI. I will try it out, and post again if I need some sample code. $\endgroup$ – celt-Ail Jul 15 '12 at 6:02
