Modelling Heterogeneity Using Bayesian Structured Sparsity

Understand

How to estimate heterogeneity, e.g.

• the effect of some variable differing across observations, is a key question in political science.
• Methods for doing so make simplifying assumptions about the underlying nature of the heterogeneity to draw reliable inferences.
• This paper allows a common way of simplifying complex phenomenon (placing observations with similar effects into discrete groups) to be integrated into regression analysis.
