FIG. 1.

Cross-tabulations of isolation results (Listeria absent and Listeria present) for Linnet and Brandt's test to compare the predictive performance of any two classifiers A and B (e.g., LR and CT models). “0” indicates a negative isolation result, and “1” indicates a positive one. b′ is the number of negative samples classified correctly by classifier B and classified falsely by classifier A and conversely for c′ samples. Analogous reasoning applies to the positive samples.
