Figure 5. A. Sensitivity (solid line) and specificity (broken line) across the range of threshold probabilities for predicting an endemic municipality. B. Positive predictive value (solid line) and negative predictive value (broken line) across the range of threshold probabilities for predicting a positive municipality. The probability threshold is the value on the continuous scale of predicted probability of transmission that is used as the cut-off for conversion into a categorical prediction of presence versus absence.
