Core Validation Services

Six pillars of independent model testing

Backtesting & Benchmarking

Compare model outputs against historic data and peer benchmarks

Systematic comparison of model predictions versus actual outcomes using statistical tests, error analysis, and peer benchmarking across industry cohorts.

Historic validation
Peer comparison
Error analysis
Statistical testing

Stress & Scenario Runs

Parametric and simulated stress testing with supervisory overlays

Governance Documentation

Full audit trails, committee-ready reports, transparency artifacts

Regulatory Alignment

GPPC, BCBS, IASB methodologies validated for compliance

Anomaly Detection

Identify model drift, bias, and data inconsistencies

Independent Assurance

External auditor and quant sign-off support
