    RAGE: A Java-implemented Visual Random Generator

    Get PDF
    Carefully designed Java applications turn out to be efficient and platform independent tools that can compete well with classical implementations of statistical software. The project presented here is an example underlining this statement for random variate generation. An end-user application called RAGE (Random Variate Generator) is developed to generate random variates from probability distributions. A Java class library called JDiscreteLib has been designed and implemented for the simulation of random variables from the most usual discrete distributions inside RAGE. For each distribution, specific and general algorithms are available for this purpose. RAGE can also be used as an interactive simulation tool for data and data summary visualization.

    Fast Generation of Discrete Random Variables

    Get PDF
    We describe two methods and provide C programs for generating discrete random variables with functions that are simple and fast, averaging ten times as fast as published methods and more than five times as fast as the fastest of those. We provide general procedures for implementing the two methods, as well as specific procedures for three of the most important discrete distributions: Poisson, binomial and hypergeometric.

    An R Implementation of the Polya-Aeppli Distribution

    Full text link
    An efficient implementation of the Polya-Aeppli, or geometirc compound Poisson, distribution in the statistical programming language R is presented. The implementation is available as the package polyaAeppli and consists of functions for the mass function, cumulative distribution function, quantile function and random variate generation with those parameters conventionally provided for standard univatiate probability distributions in the stats package in RComment: 9 pages, 2 figure
