Hi Monte,
Yes, I agree. MC could be such a powerful tool for research (I've
already used it as such), but easy access to core mathematical and
graphing functions is vital. I remember a software company that used to
develop external functions and commands for HyperCard, although the name
escapes me right now, and the set of matrix functions was pretty darn
good.
It's easy to underestimate the usefulness of the mathematical
functions, particularly matrix manipulation. If matrix functions were
available, it would be possible to do multiple regression analysis ---
great for modest research projects and courseware. But matrix funtions
are also vital for generating draws from joint probability distributions;
this is a powerful way to simulate the behaviour of many natural
phenomena, and that should be of interest to those developing games.
As for graphing (and displaying data in tables), this is such a
fundamental tool for the presentation of ideas that books have been
written about it.
Thanks for offering your statistical functions, and yes, I would be
interested in having a look at them. I will certainly share mine with
members of this list as I develop them.
Regards,
Greg
