- Dataset
- Audiometry
No blocking method discontinuity is identified inside the selected cycle span, but one or more longitudinal changes require explicit harmonization conditions before pooling.
Evidence provenance: Praxis automated inference from indexed CDC/NCHS evidence
Evidence signals: source-derived
Relevant boundaries: 2011-2012 → 2015-2016 · 2015-2016 → 2017-2018 · 2017-2018 → 2017-2020
Praxis harmonization actions
- Verify merge grain, companion variables, and component-specific analytic guidance for the new file context.
- Apply cycle-specific eligibility rules and restrict the pooled analytic population to a defensible common target population.
