Include Standard Deviation accumulate function ----------------------------------------------- Key: JBRULES-3056 URL: https://issues.jboss.org/browse/JBRULES-3056 Project: Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: 5.2.0.M2 Reporter: Radoslav Husar Assignee: Mark Proctor Priority: Minor Hi guys, I think we should add the standard deviation to accumulate functions (even excel has it ;-) I went through the Jira there is no similar request, although people are asking about it on the mailing list - so why not make their lives easier? http://lists.jboss.org/pipermail/rules-users/2011-April/019494.html It can nicely reside here with others https://github.com/droolsjbpm/drools/tree/master/drools-core/src/main/jav... Edson's article on how to add custome ones http://blog.athico.com/2007/06/accumulate-functions-edson-tirelli.html If it sounds feasible assign back to me and I can try to contribute, Cheers. -- This message is automatically generated by JIRA.
