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.

Paired comparison cohort

0 / 5 entities · fixed 10-pair benchmark

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.

HSR transactions100.0%10 matched of 10

Second Request rate100.0%10 matched of 10

HSR transactions are federal premerger notifications, not a census of every U.S. merger. Second Requests are review-stage counts, not findings that a transaction was anticompetitive. The relationship does not show that filing volume causes review intensity.

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.
