SSPICE: Systematic Skip-Pattern Integrity and Consistency Engine

Provides a graph-based framework for representing, analyzing, and validating structured statistical data governed by explicit logical dependencies, including questionnaire routing and other rule-based data structures. It supports the construction and structural analysis of directed acyclic graphs, preparation of record-level data, detection and localization of logical and skip-pattern inconsistencies, and generation of variable domains and formal compatibility rules. It also provides tools for evaluating empirical closure and minimality properties of the resulting Horn theory and for supporting the correction of inconsistent statistical records.
