Sum of rows

Sum of rows

Sum of rows

My dataset looks like this

ID       X

1001     5
1002     3
.        .
.        .
1002     4
1003     3
1003     6
1003     4
.        .
.        .
1003     3
1004     2
.        .
.        .
.        .

Now I need only one ID and X value in each row. For example I need the sum of X values for the ID number 1002.

The problem is that the sequence always change. Sometimes I see the same Id number in the next three lines sometimes in the next 8 lines.

RE: Sum of rows

I'd use proc sql for this and sum X.


proc sql;
create table newtable as
select ID, sum(X) as SumofX
from yourtable
group by ID;


RE: Sum of rows

Alternatively to keep this in native SAS:-


proc summary data=dset nway;
  class ID;
  var x;
  output out=new_dset(drop=_type_) sum=;
