Bayesian Hierarchical Modeling of Social Cohesion Across National Contexts
Quick fact
A Bayesian hierarchical model treats each country as a separate but related entity, 'borrowing strength' from all countries to improve estimates for each one—especially for small or poorly sampled nations.
Why this is interesting
Can we compare how much people trust each other in different countries when surveys are worded differently and sample sizes vary? Bayesian hierarchical models offer a clever way to do just that.
