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,

    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.
