Results of SBC analysis over the entire test set (≈10⁵ parameter–observation pairs). We generated a hundred posterior samples for every element in the test set. Left column: rank histograms for the proposed statistics. Horizontal dashed lines correspond to the ±1σ range under the assumption of uniformity. Right column: difference between rank ECDF and uniform cumulative distribution function. The gray area highlights the expected 0.01–0.99 quantile range of the ECDF difference under the assumption of uniformity.
