I have problem with some SAS code. Within first weighted mean grouping by "date", I want to compute again weighted mean using "group" with by option and "w2" as weight. How can I do this?
proc univariate data=set_out;
by date;
weight w1;
VAR price;
run;
The weight
statement accepts only one variable, so you will need to use UNIVARIATE
twice:
proc sort data=have;
by date;
proc univariate data=have;
by date;
weight w1;
VAR price;
output out=want mean=mean_price;
run;
and
proc sort data=have;
by group;
proc univariate data=have;
by group;
weight w2;
VAR price;
output out=want mean=mean_price;
run;
If you don't want to sort the data use a CLASS
statement instead of BY
