Dear statalisters,
This may be a basic question, but how can you create a variable X in which
there we have the sum of the observations of the same kind of variable Y?
If variable Y has 10 integers: 8, 8, 5, 5, 5, 3, 1, 1, 1, 1 variable X would
the integers 2, 2, 3, 3, 3, 1, 4, 4, 4, 4?
Thank you a lot for any ideas.
George
