Using SAS 9.4
I ran the following code:
proc ANOVA data=have;
class TECHNIQUE;
model TIME= TECHNIQUE;
means method /hovtest welch;
run;
(technique is categorical with 4 categories and time is continuous)
From that code I get the output below. My question is if the root MSE is the same as the standard deviation? As I am being ask to report the SD as well. Thank you
