How to find the overall PR variable by using this code (lsmeans).
Note: Variable PR has for groups
I got tthe average of each group, but I'm looking for the avreage of all as well as its Standarad error.
proc mixed data=fatd; class pr CAMONTH CAYEAR CALVING_EASE herd county ; model A = pr camonth cayear calving_ease county; random herd; lsmeans pr; run;quit;
My best regards
