+10 Certainly agree that the module is relevant and my work should be interwoven into it It was very timely that you drew my attention to this. I think I should draw up an initial design for the functionality Im aiming for and possibly put it in a new thread for comment.
Im happy to do the most of the work for this (its directly relevant to my thesis). I will also look out for (and welcome any news about) other open source code that is relevant. (e.g. Im sure scipy has random number generation for many probability distributions that would be useful, and R certainly comes to mind - I dont want to "reinvent the wheel" and will have to work out what I write anew, what gets called by a wrapper and what gets called directly) The primary aim is a probability and stats module/package that has a number of stats primitives like random variables, probability distributions etc available for building algorithms of statistical signal processing (altho my background is maths, my target users are engineers that need to build algorithms easily for tracking, classification etc but only use matlab currently so it will be nice if this plays a small part in making Sage a viable alternative to matlab for these potentially new users :-) (Thanks to all for all the help to date) On Sep 5, 10:35 am, kcrisman <kcris...@gmail.com> wrote: > > (If youre into Probability and Statistics: Ive defined a Random > > Variable class and for any instance X, the expressions exp(X) or > > log(X) (or F(X) for any real function F) are well-defined random > > variables and should be returned as new instances defined in terms of > > X - but ignore this if youre not into Prob&Stats). > > This isn't relevant to the main point of this thread, but is this at > all connected to the already existing module below?
