Java lightweight mathematics and statistics components

Commons Math is a Java library of lightweight, self-contained mathematics and statistics components.

Commons Math is made up of a small set of math/stat utilities addressing programming problems like the ones in the list below:

 - Computing means, variances and other summary statistics for a list of
 numbers
 - Fitting a line to a set of data points using linear regression
 - Finding a smooth curve that passes through a collection of points
 (interpolation)
 - Fitting a parametric model to a set of measurements using least-squares
 methods
 - Solving equations involving real-valued functions (i.e. root-finding)
 - Solving systems of linear equations
 - Solving Ordinary Differential Equations
 - Minimizing multi-dimensional functions
 - Generating random numbers with more restrictions (e.g distribution, range)
 than what is possible using the JDK
 - Generating random samples and/or datasets that are "like" the data in an
 input file
 - Performing statistical significance tests
 - Miscellaneous mathematical functions such as factorials, binomial
 coefficients and "special functions" (e.g. gamma, beta functions)
