Data intervening in the computation of the SELFI posterior. (Left panels) Observed and simulated summary statistics for Model A (well-specified; upper panel) and B (misspecified; lower panel). For each population, the simulated summaries are shown in grey and their means are represented as dotted coloured lines. The shaded areas correspond to ±2σ around their mean. The solid black line corresponds to the observations Φ_O. The binning is indicated by the vertical dashed lines. Right panels: covariance matrices for Models A and B. For each (k, k′) entry, the colour scale represents the covariance between the k-th and k′-th modes. The diagonal blocs of the full covariance matrix correspond to the intra-population covariance; the extra-diagonal blocs correspond to the inter-populations covariances.
