Hi,
I have a need to create a filter similar to the one in IBM SPSS. In IBM SPSS there is a function
@offset. It compares the current value with the value in the next row or previous row.
More details about
@offset are at the following link.
http://tech.oscarvalles.com/2010/11/using-offset-in-spss-clementine/Is it possible to create a similar function in RapidMiner.
Basically what I want to do is:
If (value of column x of current row = to value of column x or y of a differnt row)
then (calculation etc).
Thanks
