How to find residual SD/variance and plot studentized residuals using proc mixed

[Arthur2]

Hi,

I'm using the following code.

ods graphics on;
ods output lsmeans=estimate_1
diffs=diff_1;
proc mixed data = mydata (where=(treatn in (1,2,3))) plots=all;
by atype paramcd avisitn avisit;
class treatn;
model aval = treatn avisitn base;
lsmeans treatn / pdiff=control('3');
run;
ods output close;
ods graphics off;

Need to know how to get residual SD/variance and plot studentized residuals using proc mixed

Since your model doesn't involve any RANDOM component, you could just as well use proc glm and take advantage of the OUTPUT statement that will provide studentized residuals.
