prevalence 0.4.0 / download & installation


The prevalence package provides Frequentist and Bayesian methods useful in prevalence assessment studies. Several methods are available for estimating True Prevalence (TP) from Apparent Prevalence (AP).

Version 0.4.0 of the prevalence package is available on CRAN. Source code of the development version is on GitHub.

This is how you can install the prevalence package in R:

  • install.packages("prevalence")

Finally, to attach prevalence to your R session, simply run

library(prevalence)
