Hi Gang,
Thank you for your response. The variables listed as 0's and 1's are categorical (they dictate the site of data collection), thus I did not list them under qVars. Do I need to list them as a factor somehow?
Also, I am only interested in the covariate effect of my quantitative variables, so I believe I do not need to center them.
I thought my quantitative variables were also my within-subject variables. The only variable I am trying to compare between groups is latent_class. The rest of my variables are covariates.
Best,
~Brittany
