Hi!
I'm new to this list, so please be patient if my question isn't the way it
should be.
following problem:
I have data like:
id bid time
1 1 1
1 3 3
1 4 2
1 8 4
1 10 5
1 12 6
1 14 8
1 17 7
2 5 1
2 6 2
2 9 3
And I want to calculate things like max, mean or rank:
*) by id
*) stepwise inside the id's
That means f.e if in line 3 of id x I want to create an value that expresses
max(bid[1] bid[2] bid[3]).
So generally speaking a stepwise func(bid[1] ...bid[n]) foreach single n, by
id.
As far as I have seen the sw command is only usable by regression commands.
thanks
Robert
