How to include missing values as one of the "classes" in proc anova

Hi all,

The question is a pretty simple one and in the title.

I am trying to run a simple one-way ANOVA and grab some means while I am at it. However, I have 161 individuals who are missing information on Trichot_1yr. I would like to make this one of the classes that SAS uses to check the means against. Is this possible?

proc anova data=sub.master_dataset053019 ;
class trichot_1yr;
model  income_house=trichot_1yr ;
means trichot_1yr/ lsd tukey cldiff;
run;

Recode your Missing to 99 or a different value? That's the easiest solution I'm aware of.

That's what I was thinking as well. I just didn't know if there was a built in command for it. Thanks for the quick reply, Reeza.

No command as far as I know.
