Dear FreeSurfer experts,
In my dataset, I am missing some of the clinical variable for some of the subjects. How do I represent missing variables to the linear mixed model? Should I use zero or use the mean?
It is possible to test the model fit of intercept compared to time with lme_mass_LR. Both models have one random effect.
Your sincerely
