Re: Statistical analysis extension

Hi Andrey, I have already built some wrappers around just the gsl_stats_* functions in GSL during my first cut at adding some stats functionality. Unfortunately GSL doesn't have any ANOVA functions or too many nonparametric tests (look to MacANOVA for that I guess). Please let me know what response you get back from the GSL developers if any.

Hi GSL(GNU Scientific Library) has a part about statistics. It has 27 functions. I think not to copy the names of all functions. At the moment or better - my current effort to wrap this library. However it is GPLed and I haven't received an (dis)approval from the authors. You make take a look at this library. I am going to see what netlib can provide :) Regards, Andrey ----- Original Message ----- From: "Nyk Cowham" <ncowham@mac.com> To: "George Schlossnagle" <george@omniti.com> Cc: <php-dev@lists.php.net> Sent: Sunday, January 05, 2003 7:13 AM Subject: Re: [PHP-DEV] Statistical analysis extension

Have you looked on netlib? http://www.netlib.org/

Both netlib and statlib are excellent resources for algorithms. My concern with regard to adding stat functions to PHP is that it shouldn't require users installing more than one 3rd part dependent library. There are many specialized libraries from which I can 'borrow' source code, but they would have to be managed and compiled into a single library to be a workable solution for PHP developers. Thanks for the link. Is anyone else working on an similar extension? If so it would make sense for me to collaborate. Nyk

I am now thinking perhaps the best way to go is to implement the C library of statistical recipes that I need in a library that would be compatible with the PHP license. Anyone know of an existing lib that is already available? Ideally this library should have an object oriented interface that would make it very intuitive for PHP developers to use.
