FAQPage Schema
How do I build Bayesian multilevel models in R using brms?

You can perform Bayesian regression with brms by following a structured workflow that includes model specification, prior selection, fitting, and posterior diagnostic checks for robust inference.

What is the standard workflow for Bayesian inference with brms?

The standard workflow for Bayesian inference with brms includes formula specification, data preparation, setting priors, model fitting, diagnostic checks, extracting results, and ensuring reproducibility.

How do I validate causal models with dagitty before running a Bayesian regression?

You validate causal models by using dagitty and ggdag to construct and test Directed Acyclic Graphs (DAGs) before fitting your Bayesian regression to ensure the causal structure supports robust inferences.

How do I interpret marginal effects from a Bayesian multilevel model?

Marginal effects from a Bayesian multilevel model are interpreted through clear reporting and visualization of posterior predictions, allowing you to understand the specific impact of predictors on the outcome.

Does brms support reproducible Bayesian analysis workflows with model caching?

Yes, brms supports reproducible Bayesian analysis workflows by utilizing model caching, which saves fitted model objects to avoid refitting and ensures consistent reporting of posterior results.
