Daniel Müller commented on SPARK-10697:
---------------------------------------
It really would make sense to add the lift calculation to the Association rule
mining, as the lift is one important characteristic number.
lift (X --> Y) = support ( X U Y) / (support (X) x support (Y))
See also https://en.wikipedia.org/wiki/Association_rule_learning#Lift
Could you please re-open the ticket as this feature would be really helpful?
