Mechanisms¶
- Basis-Candidate Pruning Workflow
- Because cut order matters, a purely greedy pass can be unstable
This sourceWarns that greedy stepwise variable selection is unstable and can yield fragile selected models.
- Because cut order matters, a purely greedy pass can be unstable
- Interaction Term Construction
- Its failure mode is combinatorial overfitting: generate every pairwise product on a modest dataset and some will correlate with the target by chance, inflating apparent performance and fragmenting under drift.
This sourceWarns that searching many possible interaction terms can select chance associations and overstate model performance through overfitting.

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.
