Subject: [OASIS Issue Tracker] Commented: (OFFICE-2300) ZTEST
[ http://tools.oasis-open.org/issues/browse/OFFICE-2300?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17485#action_17485 ] Andreas Guelzow commented on OFFICE-2300: ------------------------------------------ Note that the proposed resolution does not change the semantics from what is implemented in OOo, Excel and Gnumeric so there is clearly no need of changing the name. > ZTEST > ----- > > Key: OFFICE-2300 > URL: http://tools.oasis-open.org/issues/browse/OFFICE-2300 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Sub-task > Components: OpenFormula > Affects Versions: ODF 1.2 > Reporter: Robert Weir > Assignee: Andreas Guelzow > > == 6.17.86 ZTEST == > The draft specification defines the result as 1-P(-|z| <= Z <= |z|), > which is a two-tailed form. But the current implementations use a > one-tailed form. Besides a real bug in OOo, Excel and OOo return > 1-P( Z<=z) for z>=0 and > P( Z <= |z|) for z<0 > Gnumeric returns P( Z <= |z|) for z<0 too, but I do not understand the > result in Gnumeric for z>=0. > In other cases of changed semantic, for example the change from right > tail to left tail in CHIDIST, for the old version LEGACY was introduced. > Shouldn't there be a differentiation in the case of ZTEST too? I know > the specification is only about the internal names and using a prefixed > name for the old version internally is possible. But the names in the > specification give a strong hint how the functions should be named in > the UI of the applications and unique names in different applications > would make working with different applications much easier for users. -- 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
