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:	0.4.1
Date:	2022-06-03
BugReports:	https://github.com/brechtdv/prevalence/issues
Depends:	R (>= 4.0.0), rjags, coda, methods
SystemRequirements:	JAGS (>= 3.2.0) (see https://mcmc-jags.sourceforge.io/)
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 https://mcmc-jags.sourceforge.io/
