Hello,
If I have two variables called xvar and yvar, how can I generate the yvar by adding 1 if xvar is even and staying the same if xvar is odd? The yvar is initialized to be 1.
xvar yvar
2 1
3
5
6
7
8
Output wanted:
xvar yvar
2 1
3 1
5 1
6 2
7 2
8 3
I tried the retain statement for yvar but can't get the expected result. Thanks.
data have;
input xvar;
retain yvar 0;
if mod(xvar,2)=0 then yvar+1;
