Posterior distribution for two parameters. Left: parameter R0. The posterior using a model at the departmental level is much more peaked that the posteriror using a model at the national level. Right: paramer ν. There is only one curve at the national curve, but many individual posteriors at the departmental level, showing a lot of heterogeneity.
Performance of 7 algorithms. For most of the figure, the ordering is: worst ABC-SMC, the ABC-Vanilla or ABC-SMC, then permABC-Vanilla or permABC-SMC, then Under-Matching, then Over-Sampling
Performance curve of various algorithms. For most of the figure, the ordering is: worst ABC-PMC, then ABC-Vanilla and ABC-SMC, best either permABC-Vanilla or permABC-SMC
Vanilla ABC: d(x,z)<ε permABC: min_{σ∈S_K) d(y, z_σ)<ε
A hierarchical model with observations y_1, y_2,... y_K. Each y_i depends on a local parameter μ_i and on a global, shared parameter β.
