ASF subversion and git services commented on SOLR-13391: -------------------------------------------------------- Commit 6c62fbf25f13b1078bb89f3eef8386a10f197b5a in lucene-solr's branch refs/heads/jira/LUCENE-8738 from Joel Bernstein [ https://gitbox.apache.org/repos/asf?p=lucene-solr.git;h=6c62fbf ] SOLR-13391: Update CHANGES.txt > Add variance and standard deviation stream evaluators > ----------------------------------------------------- > > Key: SOLR-13391 > URL: https://issues.apache.org/jira/browse/SOLR-13391 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level. Issues are Public) > Components: streaming expressions > Reporter: Nazerke Seidan > Priority: Minor > Labels: pull-request-available > Fix For: 8.1 > > Time Spent: 2h 20m > 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
