baggr (version 0.8)

Bayesian Aggregate Treatment Effects

Description

Running and comparing meta-analyses of data with hierarchical Bayesian models in Stan, including convenience functions for formatting data, plotting and pooling measures specific to meta-analysis. This implements many models from Meager (2019) .
