Residual size versus root-location error
Compare residuals near simple and double roots at the same candidate locations to illustrate why a small residual can have different interpretations.
Proposed original example. Source release and any execution are separate steps.
How does a multiple root change the relationship between residual magnitude and distance to the known root?
The root is exactly one; record candidate distance and both analytical polynomial residuals on the fixed grid.
What you could produce
- A scoped observations JSON record and a comparison with the stated reference.
Before you use it
- Python 3.13 standard library
Limits to keep in view
- No research code was executed by the preparation tool.
- Author output cannot issue an independent scientific-verification result.
