Hello,
i have this data:
Index Open High
1 4 5
2 6 7
3 8 9
Now i want to generate a new Attribute like
Open[2] - High[1]
In words: I want access data in a Row before, not in the same Row, like Open-High.
Is there a Array-Operator so i can access the data before?
Tank you verry much!
Best Regars,
Andrea

Dear Andrea,
The operator Lag from Time Series extension is able to shift the examples by n. Afterwards youi can go for a Generate Attributes.
