Version 1.1.0 Edited on December 12, 2022, to use the new as_draws_df() workflow. Preamble In Section 14.3 of my ( 2020) translation of the first edition of McElreath’s ( 2015) Statistical rethinking, I included a bonus section covering Bayesian meta-analysis. For my ( 2020) translation of the second edition of the text ( McElreath, 2020), I’d like to include another section on the topic, but from a different perspective. The first time around, we focused on standardized mean differences.
