[jira] [Commented] (SPARK-10697) Lift Calculation in Association
Rule mining
[ https://issues.apache.org/jira/browse/SPARK-10697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16447898#comment-16447898 ]
Mourits de Beer commented on SPARK-10697:
-----------------------------------------
Hello - is this still in progress?
We require the lift of an association rule for a production use case. We can solve it for our own end, but it would be more elegant to build the lift method into the AssociationRules class, and it feels like that should be fairly trivial. Surprising (yet understandable) that it's been unresolved for 2.5 years.
If a pull request is still necessary, I'll be happy to figure it out.
