- Ground Truth
- And there is a recognition of ground-truth-as-construct: the reference channel is itself produced by some procedure — a human labeller, a biopsy, a survey instrument — and is subject to its own error structure, which propagates into all derived scores.
This sourceShows a reference standard is itself a fallible construct whose error (and its dependence structure) propagates as bias into every derived accuracy estimate.
