Subject: [OASIS Issue Tracker] Updated: (OFFICE-2298) TTEST
[ http://tools.oasis-open.org/issues/browse/OFFICE-2298?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Eike Rathke updated OFFICE-2298: -------------------------------- Affects Version/s: (was: ODF 1.2) > TTEST > ------ > > Key: OFFICE-2298 > URL: http://tools.oasis-open.org/issues/browse/OFFICE-2298 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Sub-task > Components: OpenFormula > Reporter: Robert Weir > Assignee: Andreas Guelzow > > == 6.17.80 TTEST == > A lot of problems :( > (1) All formulas miss the degrees of freedom. It is necessary for TDIST. > In case unequal variance there must be defined, whether the degrees of > freedom are made integer by FLOOR or whether they remain real. > (2) In case paired: sqrt {n-1} is wrong because it is already contained > in s_{X_1 - X_2}. > (3) In case equal variance: definition of s² is missing. > (4) In case unequal variance: definition does not meet usual > definitions. In fact it is the definition for the equal variance case, > with pooled variance. > (5) As TDIST actually returns the values of the cumulative distribution > function, the definite integral in the formulas has to be revised > together with TDIST. -- 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
