How do I display the covariance matrix from proc glimmix or proc mixed?

Question

I am using proc glimmix and proc mixed to run a linear mixed model and am trying to look at the covariance matrix to see if it looks correct. How do I print it to the results?

Answer 1

Use the covb option in the model statement.

proc glimmix data=sashelp.cars;
    model horsepower = msrp / covb;
run;
