Ranks were computed only for the methods with accuracies greater than 0.50. The lower the rank, the better the accuracy of the causal orientation method for the given gold standard. The computation of rank took into account statistical variability, e.g. accuracies 0.647 and 0.645 obtained by the two IGCI methods in the ECOLI gold standard are statistically indistinguishable; that is why they have the same rank value.
