Hi,
I have a dataset called A:
Count | Percent
0 | 0.05
2 | 0.15
5 | 0.20
... .....
How can I obtain a dataset called B, where Cumulative Percentage for Count = 5 is the Percentage for Count <= 5:
(p(Count = 0) + p(Count = 2) + p(Count = 5) = 0.05 + 0.15 + 0.2 = 0.4)
Count | Perenct | Cumulative Percent
0 | 0.05 | 0.05
2 | 0.15 | 0.20
5 | 0.20 | 0.40
... ... ...
Thanks!
Are you using IML?
My assumption is you're looking to calculate the cumulative value?
If so, something as simple as:
retain cum_percent;
cum_percent = sum(cum_percent, percent);
Use the CUSUM function:
proc iml;
percent = {0.05, 0.15, 0.2, 0.4, 0.2};
cusum = cusum(percent);
print percent cusum;

Hi,
Any kind of procedure if works would be great! And I just tried yours in a data step, and got what I have. Thanks!
I'm not sure how you're calculating those numbers in the first place, but if using proc freq/means/tabulate you should be able to calculate the cumulative directly.
