Hi,
few months ago I developed a wrapper around 2 scientific libraries.
DCDFLIB (Library of C routines for Cumulative Distributions Functions,
Inverses, and Other parameters)(by Barry Brown and James Lavato)
and RANDLIB (by Barry Brown, James Lavato and Kathy Russell).
I was asked to create the wrapper by a Mr. Ed Luschei from University
of Wisconsin - Madison WI. He is a weed ecologist. The site of the
"Weed ecology" group is :
http://weedecology.wisc.edu/ . The wrapper is available here :
http://www.hristov.com/andrey/projects/php_stuff/stats/
and can be downloaded from this url :
http://www.hristov.com/andrey/projects/php_stuff/stats/stats.tgz
There is previous an effort to wrap the library by 2 scientist of UCLA :
Arno Ouwehand and Jan de Leeuw . Their implementation however is worse
since they do not validate the input parameters. In their code there
are available numerous problems that may lead to segmentation fault.
Thus I decided to rewrite the wrapper and use different function names
according to PHP's coding convention for function naming.
The documentation of the 2 UCLA's scientist can be used as reference :
http://www.jstatsoft.org/v02/i01/statistics.pdf .
I propose this wrapper to be added to PECL.
Any comments/suggestions are welcome!
Thanks,
Andrey Hristov
P.S.
AFAIK the two wrapped libs are in Public Domain therefore there is
not license problem.
