West02, Jones on End-to-End Accuracy Standards, Slide 5
- Legal false positives
- marks that are reliably detectable or marginal but are not acceptable.
- Legal false negatives
- marks that are reliably ignored or marginal but are acceptable.
- Miscounted votes, from a legal perspective
- legal false positives plus legal false negatives!
- Unless we know the frequency of different markings, and their intent, the area of the miscounted region (shaded above) is meaningless!
