Revision history for Perl extension Statistics::Descriptive.
2.6 October 10, 2002
- Fixed caching in trimmed mean and modified code to allow trimming
0% from upper bound. Formerly if 0 was requested then it used the
lower bound!
- POD format patch from ddunlap
2.5 Wednesday, May 12 1999
- Forgot to document change in v2.4, which included fixing
percentile so that it worked right and added to the test
harness.
- Modified frequency_distribution so that specific bins could
be passed in. Fixed caching so that it actually works
(it only used to get stuck returning the result of the
first call).
- Turned off caching for least_squares_fit because there's no
way to generate a unique key for memorization.
2.3 Thursday Nov 12 1998
- Fix for frequency distribution.
Changed Makefile.PL to ease ActiveState distribution of the module.
Andrea's code for preventing division by zero and other
improvements. He also wrote a great test bench.
Added code from Warren Matthews to calculate percentile.
