Exact relationship builder

Indicator comparison lab

Compare two measures while keeping their entities, periods, units, and source populations visible. A visual association does not establish causation.

Select a point, then add it or its nearest exact-pair peers.

The cohort changes the overlay and exact export only. Full-slice medians, correlation, quadrants, and coverage remain fixed.

Coverage diagnostics

What entered the plane, and what did not

Pairing coverage is reported separately for each indicator denominator. A matched row is not evidence that either source covers the full underlying economy.

Industry HHI100.0%679 matched of 679
Industry CR475.7%679 matched of 897

A NAICS industry is a statistical classification, not a legally defined antitrust market. Use these national revenue concentration measures to screen where deeper product and geographic market analysis may be warranted, not to infer market power or liability. The relationship is descriptive and does not make a statistical industry equivalent to a legal antitrust market.

Slice ledgers

Period and group structure

Counts and correlations stay inside exact paired rows. Small groups may be too thin for a stable descriptive association.

Reusable comparison packet

Carry the exact contract into analysis

The endpoint returns every matched row in the filtered slice, both observation identifiers, both source routes, evidence status, confidence, entity, group, and period.

This lab compares only declared same-entity, same-period pairs. Missing sides are excluded rather than imputed, correlation remains descriptive, and unlike universes are never combined into a composite market-power score.

Relationship directory

15 declared planes, no arbitrary joins

Each route names both measures and its exact pairing rule. Select a plane to rebuild the lab around that bounded universe.
