About the MeRGE Expo

A Bayesian population pharmacokinetic analysis workflow using Stan/Torsten and the MetrumRG Ecosystem (MeRGE).

The Expo demonstrates using bbr.bayes and Stan/Torsten in a typical Bayesian (Bayes) population pharmacokinetic (popPK) modeling and simulation (M&S) analysis, which includes, model fitting, model evaluation, and model summarization. This demonstration uses the same processes and suite of tools used at Metrum Research Group (MetrumRG) to ensure traceable and reproducible pharmacometrics research; however, it is not meant to be a complete vignette on using all of the features of bbr.bayes or the other tools used in the workflow. Links are provided in the tools section of the expo with additional information about each of the tools used.

This analysis was performed on Metworx, our platform as a service (PaaS) for high-performance, elastic cloud computing; however, Metworx is not a requirement to use the tools and process illustrated here.

This Expo demonstrates how to get started with the suite of tools used at Metrum Research Group (MetrumRG), ensuring traceable and reproducible pharmacometrics research. Step-by-step, we proceed through fitting a simple non-linear mixed effects model using Bayesian (Bayes) estimation in Stan/Torsten. We chose this example to illustrate a functional workflow of these tools with an understanding that some standards (e.g., sample sizes, etc) are simplified relative to the complexities of many typical analyses.
