Hi Statamembers,
Is there an easy command to sum the values of all observations of a
variable. I've searched the internet for info, but haven't found anything yet.
For example:
ID bmi
1 26
2 18
3 20
SUM bmi = 64
. summarize bmi
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
bmi | 3 21.33333 4.163332 18 26
. display r(sum)
64
Another way:
. egen sumbmi = sum(bmi)
