for me I am the first to study this distribution. So effect size doesn't exist. So it seems I cannot estimate the power of my hypothesis test. Right? (using p-values/t-test)
For post hoc effect size calculations, how do you determine the effect size value you input into the first box? Is it an average effect size you found in the literature, or from after having conducted your analyses, or what you want it to be?
