Derived Statistical Distributions (Mathematica Guide)

Derived distributions are modifications to existing distributions. There is a variety of ways in which you can arrive at modified distributions, including functions of random ...

Generalized Input (Mathematica Guide)

Mathematica's unique structure allows a generalized notion of input, in which not only ordinary text, but also typeset structures, diagrams, graphics, control objects and ...

Graph Measures & Metrics (Mathematica Guide)

Mathematica supports a broad range of measures that characterize graphs, from simple measures, such as the number of vertices and edges that tell the size and sparsity of a ...

Linear and Nonlinear Filters (Mathematica Guide)

Mathematica's highly optimized filtering capabilities provide a wide range of linear and modern nonlinear local filters, as well as a variety of nonlocal filters, which can ...

Presentations with Mathematica (Mathematica Guide)

Mathematica's unified computation and dynamic document architecture makes possible a new level of interactive presentation—notably allowing finished "slides" on which full ...

Urn Model Distributions (Mathematica Guide)

Urn models have a long history, starting with Laplace suggesting in 1786 that France's population be estimated by an urn-sampling scheme. They are conceptually relatively ...

Create and Use Rules (Mathematica How To)

Transformation rules in Mathematica let you set local values for symbols, functions, and all other types of expressions. Using rules provides a powerful and extensible method ...
