jamovi

Sorry for the late reply! When I specify the covariate ("age" in my case) in jamovi, it seems to work (i.e., it gives a different result as compared to when I do not add a covariate).

However, in R, when I both write and do not write the line [cov = "age"], I get the same result.

Thank you!

Thank you jonathon! I did the same analyses in jamovi online, and it seems that even when I specified the covariate in R, the results I got were still for without the covariate.

Is there anything I should revise when writing the code to include the covariate?

I am conducting a two-way repeated measures ANOVA with one covariate. My variables are:
- DV: percentage (continuous)
- 2 categorical IV: diagnosis (2 levels: yes, no) & activity (4 levels: indep.craft, inperson, online, video). activity is my focal variable here.
- Covariate: age (continuous)
