Correction of computer assessment by specialists | ||||
|---|---|---|---|---|
SLN proven | SLN disproven | Sum | ||
Software analysis | Positive findings by software | true-positive 77 (a2) | false-positive 51 (b2) | all positive findings 128 (a2 + b2) |
Negative findings by software | False-negative 6 (c2) | True-negative - (d2) | all negative findings - (c2 + d2) | |
Sum | all true SLN 83 (a2 + c2) | all false SLN - (b2 + d2) | all findings - (a2 + b2 + c2 + d2) | |
