Summary Statistics for the Scherbaum et al. (2004) Scoring System

Table S2. Summary of the statistics derived from the Central American interface dataset and ranking of the selected interface equations following the Scherbaum et al. (2004) scoring system. The results based on the normalised total (ZT), intra-event (ZA) and inter-event residuals (ZE) and associated likelihood values (LHT, LHA, LHE), are listed. The rankings for each interface equation are also presented in Table 3 of the paper.
