Binary cutoff
WebDiagnostic cut-off values for laboratory tests have generally been established based on a reference range obtained from a "healthy" population. However, there may be circumstances in which it is required to modify these cut-off values for specific pathologies. ... While the interpretation of a test with binary results is straightforward, the ... WebThe Threshold or Cut-off represents in a binary classification the probability that the prediction is true. It represents the tradeoff between false positives and false negatives .
