Is there a way that I can run a joint multivariate model that allows all intercepts and slopes to covary but does not allow level-1 residuals to covary across variables.
I am using SAS OnDemand for Academics and the following code will not run.
proc mixed data=homework3 method=ML noclprint;
class school dv;
model popst= conss const sexs sext/ noint s;
random conss sexs sext const/ sub=school type=un;
repeated dv / subject=school*pupil type= UN(1);
run;
