Hi Alik,

Thanks a lot for your suggestion, which I hoped would prompt more answers. Does anyone have suggestions on how exactly to implement the calculation of an effect size measure?

My naive answer, which perhaps will provoke Eric to provide a better one: you have the actual  cluster statistic and its permutation distribution under the null hypothesis. It seems as though that distribution could be assumed Gaussian and something like Cohen's d calculated.

Dear all,

I came across a question posted by someone about a year ago, which concerned effect size measures for cluster-based permutation tests. Unfortunately, the question does not seem to have been answered…

Q: I am using cluster-based permutation tests (depsamplesT, on time-frequency data) and am wondering how to best calculate an effect size from that.
