Hi Regina, Would it be possible or do you think there would be any merit in making a redundant function for the original FDIST function and then making two new functions for left and right? That is, we would have the following: FDIST: "Right" tail FDISTR: "Right" tail FDISTL: "Left" tail
That concept aside, I looked up the f-distribution functions in the math and engineering programs I use to see their naming conventions. Unfortunately, they offered little insight into the naming dilemma. Matlab uses: fcdf Mathcad uses: pF Maple uses: fdist (and chooses left/right tail through user inputs) I tried looking around to see if there were any other programs (especially spreadsheet programs) that might have this functionality, but my search came up empty. Sorry I couldn't be more help. Good luck, Jaron On Tue, Apr 7, 2009 at 4:48 PM, Regina Henschel <rb.hensc...@t-online.de>wrote: > Hi all, > (CC dev@sc.openoffice.org) > > with OpenFormula v1.2 we will get a new FDIST function.
