|
|
|
|
- Update to v1.3
|
|
* Changes in this version include:
|
|
+ New features:
|
|
~ STATISTICS-94: "Median/Quantile": Support median and
|
|
quantile for long datatype.
|
|
+ Fixed Bugs:
|
|
~ STATISTICS-92: "TruncatedNormalDistribution": Fix the cases
|
|
where the sampler would: (1) generate a biased distribution
|
|
if the truncated bounds are fully-positive or
|
|
fully-negative; (2) infinite loop if the truncated bounds
|
|
are positive and fully below the parent distribution
|
|
positive mean value, or are negative and fully above the
|
|
parent distribution negative mean value. Thanks to
|
|
kevinmilner.
|
|
+ Changes:
|
|
~ STATISTICS-93: "TruncatedNormalDistribution": Add methods
|
|
to expose construction parameters.

|
|
|
|
- Update to v1.2
|
|
* Changes in this version include:
|
|
+ New features:
|
|
~ STATISTICS-91: "NormalConfidenceInterval": Support
|
|
confidence intervals for a normally distributed population.
|
|
~ STATISTICS-6: Add a commons-statistics-interval module for
|
|
statistical intervals. This ports and updates functionality
|
|
in org.apache.commons.math4.stat.interval.
|
|
~ STATISTICS-90: Support creation of descriptive statistics
|
|
from an array range defined using [from, to) indices.

|
|
|
|
- Update to v1.1
|
|
* Changes in this version include:
|
|
+ New features:
|
|
~ STATISTICS-88: "LogUniformDistribution": Add a log uniform
|
|
distribution.
|
|
~ STATISTICS-87: "FoldedNormalDistribution": Add a folded
|
|
normal distribution implementation with specialized support
|
|
for a half-normal distribution.
|
|
~ STATISTICS-85: Add a quantile and median implementation.
|
|
~ 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.
|
|
~ 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.
|
|
~ STATISTICS-69: "UncoditionedExactTest": Add an
|
|
unconditioned exact test for 2x2 contingency tables.
|
|
~ STATISTICS-70: "HypergeometricDistribution": Improve the
|
|
summation used for the cumulative probability functions.
|
|
~ 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.
|
|
~ STATISTICS-64: "FisherExactTest": Add Fisher's exact test
|
|
for 2x2 contingency tables.
|
|
~ 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.
|
|
~ STATISTICS-63: Add a commons-statistics-ranking module for
|
|
rank transformations. This ports and updates functionality
|
|
in org.apache.commons.math4.stat.ranking.
