clj-kdtree is a Clojure implementation of the kD-tree data structure. This type of binary tree partitions a set of points across each dimension, allowing for efficient nearest-neighbor search. It has been released as clj-kdtree on Clojars.
Statistics2 is a module that provides normal, Chi-square, t- and F- probability distributions for Ruby. It is a fork/continuation of Shin-ichiro Hara's original code; it has been updated for compatibility with Ruby 1.9 and has been released as the statistics2 ruby gem.
It is implemented as a C extension using Steven Fortune's sweepline algorithm and the original code that he published, along with some memory management improvements by Derek Bradley. It is licensed under the MIT License.
