Doug Coleman e4e6f34f0e math.statistics: Get smart about the geometric mean. Calculate it in logspace so we can use addition of small logarithms and multiplication instead of the nth root of a giant product. 2014-09-26 13:34:25 -07:00
John Benediktsson 8a2028d2c6 math.statistics: use if-zero in mean-ddof. 2014-06-10 13:06:42 -07:00

Doug Coleman 4df945e3db math.statistics: Handle some edge cases.
Remove two unused parameters.

Doug Coleman 5224fba820 math: Revert clone on median algorithm, perhaps need to revisit this. Call clump for moving-median 2013-03-24 01:14:35 -07:00
Doug Coleman bfbe6edde6 math.statistics: Median now changes the order of the sequence, so clone it first. 2013-03-24 01:08:28 -07:00
Doug Coleman 6697f3effb math.statistics: Fix histogram and collect. Histogram used each-index even when it didn't need to. 2013-03-10 12:57:48 -07:00

Doug Coleman 516549b52c basis: Try to fix the build. My profiler is hanging, but I can't figure out why. See if the build farm has the same is
sue.

Doug Coleman 2ada02726b math.statistics: Make you think about which std you want--population or sample. Hopefully use the right words everywhere. 2012-11-07 22:53:53 -08:00
Doug Coleman a4e55a3eee math.statistics: Rename full-* to population-*. Full, while somewhat descriptive of using the entire dataset, is not a technical term, while population is used in Mathematica and stats books. 2012-11-07 22:53:52 -08:00
