Hi I'm not aware of any "out-of-the-box" Oracle solution either (like STDDEV or AVG). Looks like one has to roll ones own statistical functions when it comes to calculating things like modus or median. Is anybody aware of an extension, maybe in form of an old cartridge or a pl/sql library to handle that stuff ? The problem is, that for instance STDDEV is a "normal" SQL function, if you roll your own to calculate other things, you end up having to call a pl/sql function from sql, which isn't really a performance boost.
