Subject: [OASIS Issue Tracker] Created: (OFFICE-2298) TTEST
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 Affects Versions: ODF 1.2 Reporter: Robert Weir == 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
