Hi, all. I am trying to run a two-sample ttest on a variable with a class that contains three levels. I understand that, by using a WHERE expression, I can omit the extra level. However, my code is failing me.
proc ttest data=totalmvp;
var pt0;
class unit;
where unit= ;
run;
I do not know what to place after the "unit=" in the expression. I am trying to keep levels called "offense" and "defense" while omitting a level called "special teams."
where unit in ("offense" "defense");
or if you have no missing value of unit, the following is either an option
where unit ^in ("special teams");
