Description

The prevalence package provides Frequentist and Bayesian methods useful in prevalence assessment studies. Visit http://prevalence.cbra.be/ for more information and tutorials.

Details

Package: prevalence
Type: Package
Version: 0.4.0
Date: 2015-04-20
BugReports: https://github.com/brechtdv/prevalence/issues
Depends: R (>= 3.0.0), rjags, coda, methods
SystemRequirements: JAGS (>= 3.2.0) (see http://mcmc-jags.sourceforge.net)
License: GNU >= 2

Available functions in the prevalence package:

propCI Derive confidence intervals for an apparent prevalence estimate
truePrev Estimate TP from AP obtained by testing individual samples with a single test
truePrevMulti Estimate TP from AP obtained by testing individual samples with multiple tests, using a conditional probability scheme
truePrevMulti2 Estimate TP from AP obtained by testing individual samples with multiple tests, using a covariance scheme
truePrevPools Estimate TP from AP obtained by testing pooled samples
betaPERT Calculate the parameters of a Beta-PERT distribution
betaExpert Calculate the parameters of a Beta distribution based on expert opinion

IMPORTANT: the truePrev functions in the prevalence package call on JAGS (Just Another Gibbs Sampler), through the rjags package. Therefore, JAGS has to be installed on the user's system.

JAGS can be downloaded from http://sourceforge.net/projects/mcmc-jags/
