Conventional epidemiologic analyses often rely on aggregate summaries or single-model formulations that obscure hierarchical variation and contextual heterogeneity. We present a reproducible multilevel statistical inference framework integrating Normal (age-adjusted), Poisson (count-based), and population-offset Poisson models to quantify cardiovascular mortality across nested geographic units while separating demographic effects from structural varia","authors_text":"Christopher Blaszczak-Boxe, Jose Perez-Chavez, King-Fai Li, Mohammad Russel, Sium Gebremeriam, Yuk L.
