I want to sum the observations of a column.
A
1
2
6
3
=
Total 12
proc sql;
create table want as
select sum(a=1)/count(a) as positive_alpha from have;
quit;
proc print data=want;
run;
proc print data=have;
sum a;
run;
where is the output?
May be I missed something in understanding your problem. What are you trying to do?
I want to calculate the proportions of positive alphas. So the number in my column are (0,1)
For example,
A
1
0
1
0
so, the proportion of positive alphas is equal to sum of A /number of observations(which is 4 here)=2/4
proc sql;
create table want as
select sum(a=1)/count(a) as positive_alpha from have;
quit;
proc print data=want;
run;
simplest solution, IMO:
proc sql;
/* create table want as */
select sum(a) from have;
quit;
