Re: st: RE: Question about cummulative summatories
In response to Sirenia Vazquez's question about cumulative sum, and the
reply that Gabi Huiber provided, I would like to add...
will give the overall sum (a constant), whereas,
will give the cumulative sum.
Either can be combined with -by- to partition the data into subsets.

if you have a variable x, and want another variable y=sum(x), then Stata 7's

There is a command in the spss program in which you can generate a new
variable that is the cumulative summatory of the original variable (namely
csum). I would like to know if there is a similar command or funcion in
or if there is any other way I could create that new variable.
