Hi all,
I would like to perform a simple univariate ACE model with three covariates (one continuous and two binary).
Is there a need to center any of the variables before approaching the analysis? there are no interaction effects in the model so my hunch is that I don't need to do it, but I would still like to ask to be sure...
Thank you!
Your hunch is correct. I see no need to center any variables in the scenario you describe.
