When an individual being tested has a different pre-test probability of having a condition than the control groups used to establish the PPV and NPV, the PPV and NPV are generally distinguished from the positive and negative post-test probabilities, with the PPV and NPV referring to the ones established by the control groups, and the post-test ...
In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).
F 1 score = 2 · PPV · TPR / PPV + TPR = 2 · Precision · Recall / Precision + Recall False negative rate (FNR), Miss rate = Σ False negative / Σ Condition positive Specificity (SPC), Selectivity, True negative rate (TNR) = Σ True negative / Σ Condition negative

Net present value (NPV) represents the difference between the present value of cash inflows and outflows over a set time period. Knowing how to calculate net present value can be useful when ...
Precision and recall. In statistical analysis of binary classification and information retrieval systems, the F-score or F-measure is a measure of predictive performance. It is calculated from the precision and recall of the test, where the precision is the number of true positive results divided by the number of all samples predicted to be positive, including those not identified correctly ...
The classifier then makes 9 accurate predictions and misses 3: 2 individuals with cancer wrongly predicted as being cancer-free (sample 1 and 2), and 1 person without cancer that is wrongly predicted to have cancer (sample 9).
