How to output standard deviation of residuals

[miguel_valero]

Hi everyone, I am new to SAS and I have a very simple question.

In proc reg, is there a simple way to output the standard deviation (population s.d.) of the regression residuals?

So far, I am only able to obtain this figure from two steps:

     (1) output out=example r = y; and

     (2) proc means data=example vardef=n; output out=example2 std=y;

Thank you!

Hi,

Just add MSE in proc reg model options.
