There are three types of effect size in anovaRM. They are eta², partial eta², and omega² . My question is as follows:
(1) Is the calcutation method of eta² wrong? Because the eta² value is identical to the partial eta² value when i do a 2*2*2 within-subjects rm anova
(2) Could you add a new types of effect size Generalized Eta Squared ?

Hi,
1) Which version of jamovi are you using? Because we corrected the way we calculate eta^2 a couple of months ago (and we temporarily removed the omega^2 option).
2) If you make an issue on github, we can have a look. You can make an issue over here: https://github.com/jamovi/jamovi/issues.

Cheers,
Ravi
