Table 2.

The average improvement and the probabilities associated with a two-tailed, paired Student’s t-test comparing the AUC scores shown in Table 1 of FRaC with (i) LOF, (ii) one-class SVMs, and (iii) the better of LOF and one-class SVMs for each data set.

Approach Average improvement in AUC score using FRaC p-value
One-class SVM 0.082 0.000038
LOF 0.051 0.00062
max(LOF,One-class SVM) 0.022 0.088
