Mechanisms¶
- Stratified Balance Check
- Its failure mode is multiplicity: slice the sample into enough strata and some stratum will look imbalanced purely by chance, tempting a hunt for problems that are not there.
This sourceEstablishes the multiplicity risk of apparent subgroup or stratum imbalance arising by chance.

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. The single citation of this work carries no 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.
