Good morning,
Probably I am missing something very simple, but I am just a beginner in SAS...
I am trying to find a solution, how to add a variable with min (x_min) of a given variable (x) per observation (id).
My dataset looks like:
id x y
1 10 1
1 20 2
1 30 3
2 100 10
2 200 20
...
and what I need is:
id x min_x y
1 10 10 1
1 20 10 2
1 30 10 3
2 100 100 10
2 200 100 20
...
Would you be so kind to help me?
Thank you in advance!
Piotr Lewczuk
