Linear Mixed Model Output
Hello everyone,
I am trying to run a model with 2 random factors and 1 fixed effect that has 3 levels ("Editing"). At the output, I wonder if anyone can explain what "Editing(1)" and "Editing (2)" correspond to. I hypothesize that it must be some kind of contrast between levels of Editing but how can I find out which contrasts those are? Is the only way to continue on specifying contrasts and see what comes out of that? Or is my hypothesis wrong.
Thank you!

Also, If I want to report the overall effect of my independent variable before reporting the constrasts results, which one should I use? Editing (1) or Editing (2)?
Thank you!
