Hello Statalisters,
I�m trying to sum many variables by row using the -rowtotal -
function. The problem is that I need to distinguish when the resultant
sum is cero or a missing value. Do you know if there�s another command
or function that may sum by varlist and mantain the missing values
when they are present?
I�d like to generate a variable 'total' like this:
var1 var 2 var3......varN total
. 0 . . 0
1 . . . 1
. . . . .
0 1 . 1 2
.
.
.
1 0 0 1 2
Thank you very much!
Leonor
