# Commons Math

### Apache Commons Math

http://commons.apache.org/math/

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
- SolvingOrdinary 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)

This is a part of the Apache Commons Project.
