Hello everyone!
I'm fairly new to Jamovi and am using it for teaching purposes (much easier for students to use than R!).
I'm working on a course around ANOVAs and I'm quite surprised that there's no way to calculate planned interaction contrasts.
For example, I used to calculate orthogonal contrasts for each factor in an R tool (https://github.com/NicolasStefaniak/easieR):
sex [1 -1]
alcohol [1 1 -2, 1 -1 0]
and this gives me statistical values for 1st and 2nd order contrasts.
Is there a way of calculating them directly in Jamovi's planned contrasts?

Re: Interaction contrasts
no, sorry, not that i know of.
there are the different preset contrasts in the ANOVAs, but we don't have an implementation for custom ones like this.
