Binary classification results of 14 families of CEL groups.

This table summarises the binary classification results of an amalgamation of the 20 clusters shown in Table 3 into 14 amalgamated clusters that correspond to CEL families of one, two or three closely related CEL groups (as specified in the second row). The top half of the table shows the raw counts of surnames correctly or incorrectly classified according to the reference list, while the bottom half reports results of measures of classification accuracy (Sensitivity, Specificity, PPV = Positive Predictive Value, NPV = Negative Predictive Value).
