Re: [PHP-DEV] Statistical analysis extension
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 [EMAIL PROTECTED] To: George Schlossnagle [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Sunday, January 05, 2003 7:13 AM Subject: Re: [PHP-DEV] Statistical analysis extension On Saturday, January 4, 2003, at 10:38 PM, George Schlossnagle wrote: Have you looked on netlib? http://www.netlib.org/ Both netlib and statlib are excellent resources for algorithms.

I hope that this is delay because of the holidays. I will try again in few days. And if then I have no answer I will discontinue my efforts Thanks for the reply.

Re: [PHP-DEV] 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.

[PHP-DEV] Statistical analysis extension
Some advice would be appreciated: I need much better support for statistical analysis (central tendency, variance, kurtosis etc.) and financial formulae (NPV etc.) in my PHP applications. I have been using some calculation classes implemented in PHP, but I am at a point where I need the speed of C. I started writing an extension using the stat functions from GSL, but I see that the GNU license is not compatible with the PHP license, plus I am only using a tiny portion of that library. 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. It seems as though all extensions in ext/ are going to be moved under PECL so I am guessing that is where I should be targeting this library for release. Is that a good assumption to make?
