Reference Event
Definition
A reference event is the independently established event or observation against which an estimate or method is evaluated. It must match the claimed target: validating against body placement does not automatically establish performance for estimating time since death.
- Context
- Timing methods
For example, a study using recorded body-placement time tests estimates against placement, not automatically against the independently established time of death.
A study validated against body placement does not automatically validate an estimate of death. Correct arithmetic cannot repair a mismatch in reference events.
