But the problem with this is that it ignores dozens of other random distributions that are NOT normal. (One of the listings I found under normal distribution using www.xrefer.com, my newly discovered site for all the things I've forgotten since college) indicates there are several dozen mathematical distributions with names. Of these, the Poisson/binomial distribution is the most well known to me which is random also. Looking at the definition of the normal distribution, mijna'omirtamra'i selcu'o would be more accurate if verbose (and I see no reason why the two parts have to be combined into a single word), but I would be inclined to just use cunrgauso. lojbab -- lojbab lojbab@lojban.org Bob LeChevalier, President, The Logical Language Group, Inc. 2904 Beau Lane, Fairfax VA 22031-1303 USA 703-385-0273 Artificial language Loglan/Lojban: http://www.lojban.org
