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.
