- Raw events are missed - do not get at all, or do not get on time (source or communication issues).
- Raw events are not accurate - values are not accurate (source issues).
- Temporal order issues - Uncertainty in correct order of events.
- Pattern does not accurately reflect the conditions for situation (e.g. there are probabilistic elements)
- (other reasons) ?
Like the time constraints case there are various utility functions to designate the damage from either false positives or false negatives.
More on that issue - later.
