Hello Freesurfer experts, I have a question about how to determine if a covariate is important in a mixed effects model for example:
Y1 = B1 + B2(time) + B3(rand_effect1) + B4(rand_effect*time) + B5(covariate_1) +B6(covariate_2) Y2 = B1 + B2(time) + B3(rand_effect1) + B4(rand_effect*time) + B5(covariate_1)
Would it be appropriate to use the lme_mass_LR script? (the script says it is for comparing models with q and q+1 random effects).
Thanks, -E
