[jboss-jira] [JBoss JIRA] (DROOLS-3339) refactor the PMML regression model to use an external library for regressions

[Edson Tirelli (Jira)]

    [ https://issues.jboss.org/browse/DROOLS-3339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13666217#comment-13666217 ] 

Edson Tirelli commented on DROOLS-3339:
---------------------------------------

[~elmiko] there is no hard rule on this, it is up to the engineer. I think I suggested the EPIC for the general work across modules: so regression first, but then mining, and working on the data mappings, etc. For the regression itself, it can be condensed into a single ticket I think as it is not that big. 

Again, no hard rules, use whatever approach you prefer, as long as you are happy with it and it allows the scrum team to track progress.
