Hoppen2025

The data set contains Cohen's d effect sizes, variances, and study
characteristics including outcome type, feedback level, social comparison type,
number of sessions, sample type, sample size, and country. The meta-analysis
examined social comparison as a behavior change technique across the behavioral
sciences hoppen2025metaRoBMA.

datasets

A framework for Bayesian meta-analysis, including model estimation,
prior specification, model comparison, prediction, summaries, visualizations,
and diagnostics. The package fits single and model-averaged meta-analytic,
meta-regression, multilevel, publication bias adjusted, and generalized linear
mixed models The model-averaged meta-analytic models combine competing models
based on their predictive performance, weight inference by posterior model probabilities,
and test model components using Bayes factors (e.g., effect vs. no effect;

<doi:10.1037/met0000405>; Bartoš et al., 2025, <doi:10.1037/met0000737>).
Users can specify flexible prior distributions for effect sizes, heterogeneity,
publication bias (including selection models and PET-PEESE), and moderators.
