Mechanisms¶
- Deviation Residual Table
- Its honest failure mode is that a table shows magnitude, not validity: a huge residual can come from a single high-leverage observation that is distorting the fitted model rather than revealing a substantive anomaly — an influential point, not an insight.
This sourceDefines an influential observation by how materially its deletion changes the fitted least-squares model.

- Sensitivity to Case-Set Analysis
- Its strength is that it exposes the conclusions that hang on a single case or a fortunate selection — exactly the failure that small-N comparison is most prone to and least able to see.
This sourceIntroduces a diagnostic for identifying regression conclusions that depend disproportionately on a single influential observation.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
