In fact I could see much more reason for dropping LEGACY.NORMSDIST completely rather than turning it into a non-legacy function. After the above change with respect to the default values of NORMDIST, NORMSDIST(x) = NORMDIST(x) As a consequence there is no reason why, in the file format, we would distinguish between NORMSDIST and NORMDIST. While NORMSDIST would could exist in some legacy MS Excel files, when the file is converted to openformula format NORMSDIST could (should) just be translated into NORMDIST. It really does not make sense to have two versions of the same function, even if one of them can be called with additional arguments. > > Rename: > LEGACY.CHIDIST => CHISQDISTRIGHT > since this is well-defined and useful (no need to eliminate) Since CHISQDISTRIGHT is just (1 - CHISQDIST(...;TRUE())) I would question whether it is indeed useful, but that probably lies in the eyes of the beholder. Having said that, if we want to accept this as a non-legacy function, I would think that we should similarly have right tail functions for all other DIST functions. I don't think it makes sense for a standard to treat one distribution special in this regard. (IN fact if we wanted to treat one special then it should be the normal distribution rather than the chisquare distribution.) > Do similar operations for NORMSINV, NORMINV. similar comments as above > > LEGACY.CHITEST unchanged; maybe we can get more info on it. Without further info what it should be doing, at best we can emulate Excel or Gnumeric (which differ in their implementation) or OO (I don't know what that is doing). SO this is a clear case of a legacy function. > > Okay? Objections? see above Andreas -- Andreas J. Guelzow <aguelzow@pyrshep.ca>
