Subject: [OASIS Issue Tracker] Created: (OFFICE-2387) 5.18.56 PEARSON
5.18.56 PEARSON --------------- Key: OFFICE-2387 URL: http://tools.oasis-open.org/issues/browse/OFFICE-2387 Project: OASIS Open Document Format for Office Applications (OpenDocument) TC Issue Type: Bug Components: OpenFormula Affects Versions: ODF 1.2 Part 2 CD 2 Reporter: Patrick Durusau Text under Semantics reads: "Implementations should be wary of actually calculating PEARSON this way, due to numerical instability issues." "...be wary..."? Perhaps a note, if it says what those "issues" may be. BTW, in researching this function I found: http://www.statemaster.com/encyclopedia/Correlational-research It may just be a presentation issue but does the square root on the denominator extend across both of the summation signs? Oh, the resource I cite above alleges a better way to calculate this function with numeric stability. -- 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
