The Apache Commons Team is pleased to announce the availability of version 1.1
of "Apache Commons Statistics".
Apache Commons Statistics provides tools for statistics.
Changes in this version include new descriptive, inference, ranking and
bom modules:
New features:
o STATISTICS-88: "LogUniformDistribution": Add a log uniform distribution.
o STATISTICS-87: "FoldedNormalDistribution": Add a folded normal distribution
implementation with specialized support for a half-normal distribution.
o STATISTICS-85: Add a quantile and median implementation.
o STATISTICS-81: Add descriptive statistics for integer types. These allow
improved accuracy and performance for int and long data using an array or
streams over using the equivalent double implementation via primitive
conversion.
o STATISTICS-71: Add commons-statistics-descriptive module for
implementations of univariate statistics. Contains base interfaces for
statistics and implementations for individual statistics (e.g. Min, Max,
Sum, Mean, Variance) and combinations of statistics. Thanks to Anirudh
Joshi, Alex Herbert.
o STATISTICS-69: "UncoditionedExactTest": Add an unconditioned exact test for
2x2 contingency tables.
o STATISTICS-70: "HypergeometricDistribution": Improve the summation used for
the cumulative probability functions.
o STATISTICS-66: Add a Bill of Materials (BOM) to aid in dependency
management when referencing multiple Apache Commons Statistics artifacts.
The BOM should be used to ensure all imported artifacts are compatible.
o STATISTICS-64: "FisherExactTest": Add Fisher's exact test for 2x2
contingency tables.
o STATISTICS-62: Add a commons-statistics-inference module for hypothesis
testing. This ports and updates functionality in
org.apache.commons.math4.stat.inference including new support for
one-sided hypothesis testing.
o STATISTICS-63: Add a commons-statistics-ranking module for rank
transformations. This ports and updates functionality in
org.apache.commons.math4.stat.ranking.
