Fig. 5 Ordering of unequal-information catalogues under moderate sample-size imbalance. (a) Baseline and (b) minimum-size matching, for permutation-centred KSG with k = 4. The smaller A catalogue has true information 0.6 nats and the larger B catalogue 0.4 nats; correct ordering therefore requires the estimated B-minus-A difference to be negative. Each cell shows the percentage of 601 independent parent pairs with correct ordering. Matching averages five size-N_A subsets from B; at equal sizes the baseline is reused. L1 is a (1,1) Gaussian design and Q1x is a (4,3) quadratic design with one active coordinate pair. Complete results, including the opposite ordering, 0.1-nat differences, equal-information controls, raw estimates, absolute and comparison RMSE and pointwise Wilson intervals, are supplied in Online Resource 2
