www.mrc-bsu.cam.ac.uk/bugs/welcome.shtml BUGS. Link last verified September 14, 2000. "Bayesian inference Using Gibbs Sampling is a piece of computer software for the Bayesian analysis of complex statistical models using Markov chain Monte Carlo (MCMC) methods. It grew from a statistical research project at the MRC Biostatistics Unit, but now is developed jointly with the Imperial College School of Medicine at St Mary's, London. The Classic BUGS program uses text-based model description and a command-line interface, and versions are available for major computer platforms. A Windows version, WinBUGS, has an option of a graphical user interface and has on-line monitoring and convergence diagnostics. CODA is a suite of S-plus/R functions for convergence diagnostics. The programs are reasonably easy to use and come with a range of examples. Considerable caution is, however, needed in their use, since the software is not perfect and MCMC is inherently less robust than analytic statistical methods.There is no in-built protection against misuse."

http://bevo.che.wisc.edu/octave/ GNU Octave. "GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language. Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages. GNU Octave is also freely redistributable software. You may redistribute it and/or modify it under the terms of the GNU General Public License (GPL) as published by the Free Software Foundation. Octave was written by John W. Eaton and many others. Because Octave is free software you are encouraged to help make Octave more useful by writing and contributing additional functions for it, and by reporting any problems you may have."
http://www.psychologie.uni-trier.de:8000/projects/gpower.html G*Power. Link last verified September 14, 2000. "G*Power is a general power analysis program that comes in two essentially equivalent versions: one runs under the Macintosh OS and the other was designed for MS-DOS. G*Power performs high-precision statistical power analyses for the most common statistical tests in behavioral research, that is, t-tests (independent samples, correlations, and any other t-test), F-tests (ANOVAS, multiple correlation and regression, and any other F-test), and Chi^2-tests (goodness of fit and contingency tables). G*Power computes power values for given sample sizes, effect sizes, and alpha levels (post hoc power analyses), sample sizes for given effect sizes, alpha levels, and power values (a priori power analyses), and alpha and beta values for given sample sizes, effect sizes, and beta/alpha ratios (compromise power analyses). The program may be used to display graphically the relation between any two of the relevant variables and it offers the opportunity to compute the effect size measures from basic parameters defining the alternative hypothesis."

http://www.tugsg.com/qdstat/qdst_fs.htm QDStat. Link last verified September 14, 2000. "The QD of QDStat stands for "Quickly Done" although some irreverent individuals favor the term "Quick and Dirty." The package, however, remains true to either name and is an analytical tool for rapid, easy evaluation of relatively small uncomplicated data sets using procedures common to basic statistical textbooks. QDStat does not understand about three dimensional mixed designs in the Lindquist tradition (there now you know how old I am), factorial designs with confounded interactions, balanced lattice designs, balanced incomplete-block designs and similar things. Those who have need of such techniques will not be well served by QDStat and should direct their efforts to one of several other more extensive packages such as SASŪ. On the other hand, the needs of mere mortals may be met by QDStat."

Its development has been funded by ESRC and Lancaster University. In 1989, SABRE 2.0 was released, written by Jon Barry, Brian Francis and Richard Davies. SABRE 3.0, developed by Dave Stott, was released as freeware on the WWW in 1996. The current release is version 3.1. SABRE is available as freeware under the GNU general public licence on the WWW."
