  1. The table reports the performance of the seven different column comparison functions using four different methods for combining scores: summing the raw scores, computing the arithmetic mean (AM), or computing the geometric mean (GM). Each entry is the mean receiver operating characteristic (ROC) score across all queries in the simulation. The table reports results for the S/8 sampling rate. aHighest ROC in the column. ALLR, average log-likelihood ratio; ED, euclidean distance; FIET, Fisher-Irwin exact test; KLD, Kullback-Leibler divergence; PCC, Pearson correlation coefficient; PCST, Pearson χ2 test; SW, Sandelin-Wasserman function.
