Apache commons math

When increment double is used to add data incrementally from a stream of unstored values, the value of the statistic that getResult returns is computed using the following recursive updating algorithm:, apache commons math. If AbstractStorelessUnivariateStatistic.

You can download source and binaries from our download page. Please note that the last official version 3. Bug reports should be filed against the current development version.

Commons Math is a library of lightweight, self-contained mathematics and statistics components addressing the most common problems not available in the Java programming language or Commons Lang. Download the Latest Release of Commons Math. All Rights Reserved. All other marks mentioned may be trademarks or registered trademarks of their respective owners. Commons Math: The Apache Commons Mathematics Library Commons Math is a library of lightweight, self-contained mathematics and statistics components addressing the most common problems not available in the Java programming language or Commons Lang. Guiding principles: Real-world application use cases determine development priority. This package emphasizes small, easily integrated components rather than large libraries with complex dependencies and configurations. All algorithms are fully documented and follow generally accepted best practices. In situations where multiple standard algorithms exist, a Strategy pattern is used to support multiple implementations. Limited dependencies. No external dependencies beyond Commons components and the core Java platform at least Java 1.

For Monte-Carlo simulations the JDK generator does not have any of the good mathematical properties of the other generators, so it should be avoided, apache commons math. Interface extracted from java. Bug reports should be filed against the current development version.

Commons-math provides a few pseudo random number generators. The top level interface is RandomGenerator. The JDK provided generator is a simple one that can be used only for very simple needs. The Mersenne Twister is a fast generator with very good properties well suited for Monte-Carlo simulation. It is equidistributed for generating vectors up to dimension and has a huge period: 2 - 1 which is a Mersenne prime. The WELL generators are a family of generators with period ranging from 2 - 1 to 2 - 1 this last one is also a Mersenne prime with even better properties than Mersenne Twister.

The analysis package is the parent package for algorithms dealing with real-valued functions of one real variable. It contains dedicated sub-packages providing numerical root-finding, integration, interpolation and differentiation. It also contains a polynomials sub-package that considers polynomials with real coefficients as differentiable real functions. Functions interfaces are intended to be implemented by user code to represent their domain problems. The algorithms provided by the library will then operate on these function to find their roots, or integrate them, or Functions can be multivariate or univariate, real vectorial or matrix valued, and they can be differentiable or not.
