Using Stata 19 evaluators for Bayesian meta-analysis
This is a summary of a workshop Robert gave at the Italian Stata Users' Group in Milan in September 2025. Sightseeing in the Galleria Vittorio Emanuele Stata version 19, released in 2025, introduced new additional flexibility to its Bayesian capabilities which makes Stata now fully flexible for all the BMA models that we discuss in the book. This is a really important development for Stata users, though in general those who are heavily into Bayes move towards probabilistic programming languages like JAGS, Stan or PyMC, and access them through R, Python, or Julia.

Going beyond the normal assumptions in random effects models in meta-analysis?
Most meta-analyses are based on the random-effects model, the standard go-to framework based on the assumption that each study estimates a different “true” effect and that these true effects follow a normal…

Going beyond the normal assumptions in random effects models in meta-analysis?
Most meta-analyses are based on the random-effects model, the standard go-to framework based on the assumption that each study estimates a different “true” effect and that these true effects follow a normal distribution. This assumption underpins nearly every random-effects analysis performed in clinical and public-health research. But what if that assumption isn’t true? What if study results follow a skewed, bimodal, or heavy-tailed pattern?
