Package: geoDeltaAudit 0.1.0

geoDeltaAudit: Quantifying Variable Change Induced by Administrative Boundary Transformations

Tools for auditing how analytic variables change when data are transformed across administrative boundary systems. The package is agnostic to data source, variable type, and administrative geography, and is designed to quantify transformation-induced change without attributing blame to any specific boundary definition or allocation scheme.

introduction
Geographic Data Transformation Auditing: Why Variable Agnosticism Matters | The Problem in Population Health | For the first hop, we construct a ZCTA–ZIP association table by expanding the ZIP→ZCTA relationship file (i.e., grouping ZIPs by their assigned ZCTA). This produces a one-to-many mapping (ZCTA→{ZIPs}) that reflects common “lookup-style” workflows in applied settings. | Decision Points Framework | Variable Agnosticism Design
