A result of a test that shows as absent something that is present.
Diagram of a binary classifier separating a set of samples into positive and negative values. The elements in the green area on the right are those classified as positive matches for the tested condition, while those on the pink area on the left were classified as negative matches. The red crosses ( ) within the green area () represent false positives (negative samples that were classified as positive). Conversely, the green circles ( ) within the pink area () represent false negatives (positive samples that were classified as negative).
(statistics) A type II error.
The results obtained from negative sample (left curve) overlap with the results obtained from positive samples (right curve). By moving the result cutoff value (vertical bar), the rate of false positives (FP) can be decreased, at the cost of raising the number of false negatives (FN), or vice versa (TP = True Positives, TPR = True Positive Rate, FPR = False Positive Rate, TN = True Negatives).
