How to compare models that aren't listed in the output

AnaOnar

Hello,

In the attached screenshot, I would like to compare the best model (3 main effects + one interaction) to a model that contains the 3 main effects + one interaction AND also the three-way interaction. Is there a way to make this direct comparison?

Dear AnaOnar,

There is not. JASP respects the principle of marginality, which means that if you have an interaction, the constituent main effects are in there as well.

Cheers,

E.J.
