When study statistics might have a typo This post expands on subject matter of Chapter 5 of our book, on extracting study statistics for meta-analysis. Uncertainty about a published statistic is one of the most common reasons to consider…

New blog post!
How Bayesian methods can help with your meta-analysis when there is a study statistic that you suspect might be a typo. With lots of lovely code for hands-on learning, and tips on the interpersonal stuff to keep you in a job when the AI comes for you.

That way we Bayesian meta-analysts can help each other with this fascinating subject, wherever we are in the world. We are keen to include news of new developments, publications, events, etc, so please let us know if you have any news you think we should feature.

The Bayesian Meta-Analysis Network Models, code, and discussion for Bayesian meta-analysts

Breaking news!

Our new website is live at bayesian-ma.net

This is a hub for discussions related to Bayesian meta-analysis. We are adding all the code from the book (and more) over the summer. It is in a blog format so users can comment and ask questions against the relevant topic or software tool.

Bayesian Meta-Analysis: A Practical Introduction Meta-analysis is the statistical combination of previously conducted studies, often from summary statistics but sometimes with individual participant data. It is widespread in life sciences and is gai...

Come along & learn how easy it is to get started, what a fantastic range of packages you can use, and how it helps decision-making

Now on sale! 🎁 📖 You can pre-order "Bayesian Meta-Analysis: a practical introduction" from www.routledge.com/9781032451893 and all good booksellers. The book is being printed right now and will be shipped to you on 27 June 2025.

Part III: "Specific Problems" explores methods including network meta-analysis, individual participant data integration, publication bias modeling, and emerging techniques such as multivariate approaches and population-adjusted indirect comparisons.

Part II: "Getting Inputs and Crafting Outputs" addresses the practical challenges of extracting statistics from published literature, eliciting expert priors, and effectively communicating meta-analytic findings.

Part I: "The Fundamentals" establishes core statistical inference principles and Bayesian methodology, progressing through common effect and random effects meta-analysis frameworks.

We are delighted to unveil the table of contents for our forthcoming book "Bayesian Meta-Analysis: a practical introduction".

You can pre-order the book from Friday 6 June at: www.routledge.com/9781032451893

The book is organized in three parts:

StanBio Connect 2025 – StanBio Advancing Biomedical Research with Stan

Robert will be speaking at StanBio Connect on 30 May (online 1300-2000 UTC) on Bayesian meta-analysis in Stan and brms. stanbio.org

"Bayesian Meta-Analysis: A Practical Introduction", the new book by your friendly guides, Robert and Gian Luca, will be out in June on CRC Press! Here is the text from the back cover to give you an overview.
