OK I know there is an easy way to do this but cannot get my brain around it. If I have an attribute that contains integers in ascending order but they are not sequential, how do I create a new attribute that shows the difference between each example and the one before it? For example:
att1 delta
1 ?
3 2
4 1
5 1
17 12
20 3
etc..
Thanks.

Scott,
the Lag operator is your friend.
Generally speaking: All operations which requiere cross-example operations are rather in the time series extension than in core.
