*************
egen numberofones=rowtotal( var1- var11)
*************

Betreff: st: Columns of binary variable
> Dear Statalist,
> I have 11 columns of binary variables as per the example below. This may
be a very straightforward question, but is there a way to generate a new
variable that represents the number of 1's in each row for each individual?
