It constructs an average of the parameters weighted by their likelihood, providing much more reliable inference when the "true" model is unknown. 2. Causal Mediation Analysis

BMA evaluates a set of plausible regression models to calculate posterior probabilities for each one. Horizontal labels for the Y-axis and a right-hand
Horizontal labels for the Y-axis and a right-hand legend make charts immediately publication-ready.
Allows policy analysts and healthcare researchers to detangle the direct effects of a policy versus those mediated through other factors. 3. All-New Default Graphing System
Going beyond standard regression, researchers can now isolate and quantify direct and indirect causal pathways.
