Subject: [OASIS Issue Tracker] Commented: (OFFICE-3757) Public Comment: COVAR formular is missing factor 1/N
[ http://tools.oasis-open.org/issues/browse/OFFICE-3757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=30263#action_30263 ] Andreas Guelzow commented on OFFICE-3757: ------------------------------------------ I am quite sure that no implementation implements what the ODF standard currently requires, but that every implementation has a factor depending on n (the number of data pairs.) Unfortunately this factor could be 1/n (population covariance) or 1/(n-1) (sample covariance). Is suspect that implementations are using 1/n, since that is what was implemented in MS Excel, but we need to verify that. > Public Comment: COVAR formular is missing factor 1/N > ---------------------------------------------------- > > Key: OFFICE-3757 > URL: http://tools.oasis-open.org/issues/browse/OFFICE-3757 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Bug > Components: OpenFormula > Affects Versions: ODF 1.2 > Reporter: Robert Weir > Assignee: Andreas Guelzow > > Copied from office-comment list > Original author: Regina Henschel <rb.henschel@t-online.de> > Original date: 2012 15:35:56 -0700 (PDT) > Original URL: http://lists.oasis-open.org/archives/office-comment/201203/msg00000.html -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
