RE: WP 34S binomial bug?
I did a complete "Electronic" search of my uptodate personalilzed WP34s PDF manual version 3.3 and discovered that NOWHERE does the manual define the upper bound statistical/probability functions like "Binom_{u}". It describes all of the other probability functions like "Bionom", "Binom_{p}", "Binom^{1}", and even shows the mathematical formula for each of them, but completely ignores "Binom_{u}" the "Binomial Upper Bound" calculation, what it does, and how it is computed. I would think that this function should be explained in the manual like all of the others? The same omission occurs in the Cauch, Expon, F, LogNrm, Logis, Norml, Poiss, Poisλ, and t probability functions. Perhaps to those who use statistical/probability functions every day, this "upper bound" stuff is obvious/boring, but to me it was not. Does anyone have an explanation as to why the "probability_{u}" definitions/formulas were omitted from the manual? I would think that if it is important enough to put in the CALCULATOR, it would also be worth mentioning in the MANUAL. If there is a lot of similarity between the upper bound calculations among the variety of probability functions then perhaps it would only need to be defined for one of these functions with a reference (see Binom), but I found NOTHING about any of the upper bound calculations ANYWHERE in the manual. I don't want this so sound like a complaint, just a helpful suggestion as to how the manual could be improved in the future.
