Covariates for hierarchical multiple regression
I've just started to use JASP, so sorry for the silly question. I'm running a hierarchical multiple regression, but as I try to enter the variable gender as a covariate, JASP doesn't allow me to do it. Gender, of course, is a nominal dummy coded variable. However, in many tutorials I've seen that JASP does allow to do it.
Thank you for your answers.
