Default Bug#643874: RFP: python-fisher -- simple and fast implementation of Fisher's exact test

Package: wnpp
Severity: wishlist
Usertags: unige.ch-jmlab

Hi there!

* Package name : python-fisher
Version : 0.1.4
Upstream Author : Haibao Tang <tanghaibao@gmail.com>,
Brent Pedersen <bpederse@gmpail.com>
* URL or Web page : <http://pypi.python.org/pypi/fisher/>
<https://github.com/brentp/fishers_exact_test>
* License : BSD
Description : simple and fast implementation of Fisher's exact test
Fisher's exact test is a statistical significance test used in the
analysis of contingency tables where sample sizes are small.
.
This package implements the Fisher's exact test as a Python Extension
Module.

I cc:ed the debian-python@l.d.o mailing list, maybe someone there is
interested in packaging it.

The src/cfisher.pyx file contains the following statement:

"some of this code is originally from the internet. (thanks)"

I also cc:ed the upstream authors for their comments on that sentence,
FTR the file contains references to three URLs, so I guess this is the
code taken from the Internet. What is its license?

l009: Logarithm of n! with algorithmic approximation
Reference:
Lanczos, C. 'A precision approximation of the gamma function',
J. SIAM Numer. Anal., B, 1, 86-96, 1964."

l097: http://docs.cython.org/docs/special_methods.html
< 0 | <= 1 | == 2 | != 3 | > 4 | >= 5

l157: found these tests on this ticket. (thanks).
http://projects.scipy.org/scipy/ticket/956
these values were taken from R as a means to test the code in that ticket.

Thx, bye,
Gismo / Luca
