Issues are Public) > Components: streaming expressions > Reporter: Nazerke Seidan > Priority: Minor > Labels: pull-request-available > Time Spent: 1h 50m > Remaining Estimate: 0h > > It seems variance and standard deviation stream evaluators are not supported > by any of the solr version. For example, > let(echo="m,v,sd", arr=array(1,3,3), m=mean(a), v=var(a), > sd=stddev(a)) > So far, only the mean function is implemented. I think it is useful to have > var and sttdev functions separately as a stream evaluator. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
