# st: Question about cummulative summatories

 From Sirenia Vazquez To statalist@hsphsun2.harvard.edu Subject st: Question about cummulative summatories Date Tue, 29 Jul 2003 12:54:58 -0600

```I have a variable x with 10 observations x =(x1, x2,...,x10), and I want to
create a new variable y = (y1, y1,....y10) in which y1=x1, but that y2= x1+x2;
y3=x1+x2+x3; and so on, until y10= x1+x2+...+x10.
Is there any command in Stata that does that?
