Table 2. Example of a confusion matrix showing the prediction accuracy of the Bayesian belief network (BBN) beta model in Fig. 3a used with the case data file in Table 1. The confusion matrix shows the number of known cases that were correctly classified, here as whether the species was actually present or absent, given the conditions on each site.
