Approximate Bayesian Computation and Simulation-Based Inference for Complex Stochastic Epidemic Models
Approximate Bayesian Computation (ABC) and other simulation-based inference methods are becoming increasingly used for inference in complex systems, due to their relative ease-of-implementation. We briefly review some of the more popular variants of ABC and their application in epidemiology, before using a real-world model of HIV transmission to illustrate some of challenges when applying ABC methods to high-dimensional, computationally intensive models. We then discuss an alternative approach—history matching—that aims to address some of these issues, and conclude with a comparison between these different methodologies.

- Supplement A: Bisection method. Details the bisection method used to generate tolerances at each generation of ABC.
- Supplement B: Approximate posterior distributions for ABC vs. nonimplausible region for HM. Plots of the approximate posterior distributions after 11 generations of ABC, and depth plots after 9 waves of history matching. (Note that HM does not produce posterior samples, rather these correspond to the densities of nonimplausible points.).
