jfa is an R package that provides statistical methods for auditing. Its functionality and intended workflow are implemented with a graphical user interface in the Audit module of JASP (https://jasp-stats.org), a free and open-source software program for statistical analyses.

This is the source code for Statistical Audit Sampling with R (SASR), a (work in progress) book intended as a practical guide to Bayesian and classical auditing in the programming language R, with hands-on examples. Read the full book at https://koenderks.github.io/sasr.
