I wish to calculate the LEVERAGE measure after the Association Rule Learner (Borgelt) Node.
This could be done applying the following formula in the Math Formula Node:
( $AbsoluteBodySetSupport$/1001 * $AbsoluteHeadItemSupport$/1001)
The only problem is that I have to code “1001” as the total number of transaction.
Could it (easily?) taken from a previous node (in my example, the Cell Splitter)?
