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. 2.2 Monday Feb 23 1998 - Multiple bug fixes: Fixed min/max bug with '0' vs defined. Provided fix for bug with AUTOLOAD/DESTROY/Carp problem. 2.1 Tues Sep 02 1997 - Multiple bug fixes: Cleaned up syntax error with my scoping.
