The DALY Calculator is a free, open-source Graphical User Interface for stochastic disability-adjusted life year (DALY) calculation, developed in the R environment for statistical computing. The main goal of the DALY Calculator is to provide a flexible and easy-to-use tool for DALY calculation, and to promote consistency in the uncertainty analysis of DALYs.

@RISK performs risk analysis using Monte Carlo simulation to show you many possible outcomes in your Microsoft Excel spreadsheet—and tells you how likely they are to occur. This means you can judge which risks to take and which ones to avoid, allowing for the best decision making under uncertainty.

Minitab is the leading provider of software for statistics education and Lean, Six Sigma, and quality improvement projects. For nearly 40 years, Minitab has been helping world-class organizations analyze problems, transform their business, and train their students.

OpenEpi is free and open source software for epidemiologic statistics. It can be run from a web server or downloaded and run without a web connection. A server is not required. OpenEpi provides statistics for counts and measurements in descriptive and analytic studies, stratified analysis with exact confidence limits, matched pair and person-time analysis, sample size and power calculations, random numbers, sensitivity, specificity and other evaluation statistics, R x C tables, chi-square for dose-response, and links to other useful sites.

BetaBuster is a GUI that can be used to obtain specific Beta prior distributions for Se, Sp and Prevalence. BetaBuster was designed by for the purpose of obtaining specific Beta prior distributions based on scientific input for quantities like the sensitivity or speciticity of a diagnostic test.

The following modules contain software, program code, illustrated examples, and associated publications. The purpose of the program is to make available to a larger audience some of the methods developed in addressing issues of analyzing data derived from imperfect diagnostic tests. These programs have mainly been written for use with WinBUGS, to facilitate their use by data analysts.

The TAGS software can be used to estimate the sensitivity of two or more diagnostic tests in the absence of a gold standard, provided two or more populations with differing prevalences can be cross-classified based on diagnostic test results. The algorithm in the TAGS software follows the frequentist paradigm and utilizes Newton-Raphson and EM algorithms to generate maximum likelihood estimates.

The BUGS (Bayesian inference Using Gibbs Sampling) project is concerned with flexible software for the Bayesian analysis of complex statistical models using Markov chain Monte Carlo (MCMC) methods. The project began in the MRC Biostatistics Unit and led initially to the `Classic' BUGS program, and then onto the WinBUGS software developed jointly with the Imperial College School of Medicine at St Mary's, London. Development now also includes the OpenBUGS project in the University of Helsinki, Finland.
