Omega Squared Simple Effects (GLM)

Post by ijansse »

Hello!

I am using GLM for my analyses and I am wondering why JAMOVI does not calculate effect size (such as omega squared) for my simple effect analyses. Is it simply not possible or how can I get there?
Help is urgently needed!

Thanks!

I.

Hi
not at the moment (it will come soon). However, you can compute the effect sizes based on the F and df you find the output. For the partial eta-square, you simply go like this: if you have F(df1,df2)=f, peta=f*df1/(f*f1+df2). For omega, you can check the formula here https://www.aggieerin.com/shiny-server/tests/omegaf.html.
