Introduction

The R community has developed packages for a Bayesian (Bayes) modeling workflow. Metrum Research Group designed the bbr.bayes to integrate into this modular workflow and make it easier to leverage these tools when doing Bayes modeling with NONMEM®. All these tools are free and open-source.

Posterior

Provides tools for working with output from Bayes models. bbr.bayes::read_fit_model() reads in output from NONMEM® and formats it as a posterior::draws_array object required by the posterior package.

Tidybayes

Integrates Bayes modeling with the tidyverse and ggplot.

Bayesplot

Plotting Bayes models and diagnostics with ggplot.

LOO

Efficient computation of the leave-one-out (LOO) information criteria for model evaluation.
