BUGS. Bayesian inference using Gibbs
sampling. The most important software package for making Bayesian methods
accessible to most users. Alastair Stevens, Cambridge University.
interactive statistical analysis program in the spirit of S for Macintosh, DOS/Windows and
Unix. Strengths are analysis of variance and related models, matrix algebra, time series,
and to a lesser extent exploratory statistics. Gary Oehlert and Christopher Bingham,
University of Minnesota.
The R Project. Language very similar to S. Originally
developed by Robert Gentleman and Ross Ihaka at the University of Auckland and now continued by a larger team.
ADE-4. Analysis and graphics
package for ecological data analysis on Macintosh or Windows 95. University of Lyon.
AM Statistical Software. Software from
the American Institutes for Research for analysing data from large-scale
Arc. A package for regression
analysis designed as a companion to the book Applied Regression Including
Regression and Graphics by R. D. Cook and S. Weisberg. Essentially a
front-end to Xlisp-Stat, it contains many
graphical methods unavailable in any other program. The ability to implement
interactive graphics is a particular strength. For Windows, Macs and
Unix. Sanford Weisberg, University of Minnesota.
BrightStat. A webbased statistical
package by Daniel Stricker, University of Bern.
statistical analysis and graphics package with command line and GUI. James Filliben, Alan
Heckert and Robert Lipman, National Institute of Standards and Technology.
EMMIX. Fortran software
to fit mixture models. Geoff McLachlan, University of Queensland.
ESS. Emacs Speaks Statistics. Offers a
common interface through EMACS to many statistical packages. A.J. Rossini, R.M. Heiberger,
K. Hornik and M. Maechler.
Factor. Exploratory factor analysis.
Rovira i Virgili University, Spain.
IDAMS. Information processing
tools, data mining and statistical analysis. A statistical program developed
and distributed by UNESCO. The emphasis is on exploratory multivariate
techniques but basic methods such as one-way ANOVA and regression are also
included. Manual and considerable documentation available online.
jamovi is a free statistical spreadsheet with backend computations performed in R.
Can output the R code used to perform any analysis.
computing environment for statistics and interactive graphics. Luke Tierney, University of Iowa.
Computes person-years and standardized mortality ratios. Dirk Taeger, University of
Pan-Data CCOUNT. A
package for market research analysis including data evaluation, cross
tabulation etc. Volker Hoffmann.

email. Gonzalo Sánchez-Crespo, Delegacion INE.
Program Mark. Advanced
mark-recapture modelling. Gary White, Colorado State University.
PS: Power and Sample
Size. A stand-alone program which does power calculations for two
samples, linear regression and for survival responses. William Dupont and
Walton Plummer Jr, Vanderbilt University Medical Center.
Octave. A language designed for
numerical linear algebra.
Mathematical modelling for the Macintosh. Regression modelling including nonlinear
functions and bootstrapping. The site includes a compendium of probability
distributions and a guide to mathematical modelling. Mike McLaughlin.
A calculator that computes table values for many probability distributions.
K. Krishnamoorthy, University of Louisiana at Lafayette.
Statistics101. A Java
implementation of the “Resampling Stats” programming language developed by
Julian Simon and Peter Bruce (http://www.resample.com).
Runs on any platform which supports Java 1.4 or higher including Windows,
Mac and Linux. Presented as “giftware”
rather than freeware. John Grosberg.
Statlets. An web accessible statistical package
written in Java. Free for small data sets with no more than 10 variables or 100 cases. NWP
STATS. Windows program which computes
basic two sample statistics. Decision Analyst Inc.
|Stat. Data analysis on
Unix and DOS. Gary Perlman.
TimesLab. Current version of the MS-DOS
time series analysis program which accompanied the book TIMESLAB: A Time Series
Analysis Package by H. Joseph Newton, Wadsworth, Pacific Grove, 1988. The software is
now freely available from the WWW site, but you will still want the book. See also the
S-Plus version at the Statlib S archive.
ViSta. Visual tools for
data analysis, written in LispStat. Forrest Young, University of North Carolina, Chapel
statistical methods and data exploration. Currently available for various Unix flavours
with Windows on the way. Site includes extensive online help and Java and CGI interfaces
to the package. Institute of Statistics and Econometrics, Berlin.
Xpro. Windows software for exact parametric inference.
Xtremes. Graphics and analysis
program for MS-Windows which comes with the book Statistical Analysis of Extreme
Values by R.-D. Reiss and M. Thomas, Birkhauser Publishers, Basel, Boston, 1997. Free
demonstration available but without online help or data sets. Rolf-Dieter Reiss,
University of Siegen.
