Dear list members,
A new package, called *prevalence *(version 0.1.0), is now available on
CRAN: http://cran.r-project.org/package=prevalence
This package provides Frequentist and Bayesian methods useful in
prevalence assessment studies. More specifically, the following
functions are currently available:
* truePrev -- Bayesian estimation of True Prevalence from Apparent
Prevalence obtained by testing /individual /samples
* truePrevPools -- Bayesian estimation of True Prevalence from
Apparent Prevalence obtained by testing /pooled /samples
* propCI -- Calculate confidence intervals for a prevalence estimate
* betaPERT -- Calculate the parameters of a Beta-PERT distribution
* betaExpert -- Calculate the parameters of a Beta distribution based
on expert opinion
Function 'truePrev' is also implemented in an online Shiny app:

The development version is on GitHub:
https://github.com/brechtdv/prevalence/
Comments and suggestions would be greatly appreciated.
Best wishes,
Brecht and coauthors.
