Hi!
I want for each observation i , ai's sorted according to ki's.
So a1 a2 k1 k2
1 2 -1 -2
If I do sortrows a1 a2 --> I would get a1 a2
1 2
If I do sortrows k1 k2 ->> I get k1 k2
-2 -1
but what I want is a1 a2 k1 k2
2 1 -2 -1
This is what the new program does.
Ummmm do I make it clear now ? Please email me again if you don't get me.
Thank you,
Ashim.
