Catastrophe Model Validation Framework
Validate catastrophe models systematically with AI-driven analysis and stakeholder reports
What You Can Do
This skill automates the validation of catastrophe models by analyzing your data inputs, reviewing model assumptions against industry standards, identifying gaps and risks, and generating comprehensive validation reports ready for stakeholder review. You get systematic documentation of model strengths, weaknesses, and recommendation priorities—accelerating your pre-deployment sign-off, regulatory audits, and annual recalibration cycles.
Features
Systematically review model assumptions (hazard distributions, correlation matrices, valuation methods) against your input data and industry benchmarks. Identify contradictions, outdated parameters, and areas needing recalibration.
Evaluate completeness, accuracy, and alignment of your model inputs (historical loss data, exposure data, peril parameters). Flag missing values, outliers, and data inconsistencies that could skew model output.
Systematically test how model output changes across parameter ranges and extreme scenarios. Document which assumptions have the highest impact on risk estimates and return probabilities.
Compare model outputs against historical performance, peer benchmarks, and regulatory thresholds. Identify discrepancies and flag outputs that fall outside expected ranges.
Validate that all material risk factors (geographic concentrations, line-of-business correlations, gross/net adjustments) are correctly represented in model structure and parameter values.
Generate executive summaries, detailed validation findings, recommendation matrices, and compliance documentation formatted for auditors, regulators, and senior management sign-off.
Systematically extract and organize model specifications, assumption justifications, and validation evidence into a centralized, searchable validation workbook.

Validation Report Header:
- Model: ABC Catastrophe Model v2.4
- Validation Date: 2026-08-09
- Status: CONDITIONAL APPROVAL (3 findings, 2 recommendations)
Key Findings: ✓ Hazard frequency assumptions aligned with 50-year historical record ⚠ Wind correlation matrix based on 2010 data—recommend 2020-2026 recalibration ✗ Flood loss severity cap ($500M) exceeds observed 1-in-250 tail estimate by 15%
Data Quality Summary:
- Historical Loss Records: 100% complete, no outliers flagged
- Exposure Data: 94% populated; 6% missing latitude/longitude in commercial portfolio
- Assumption Parameters: 87% peer-aligned; 3 parameters deviate >20%
Recommendation Priority Matrix:
- [HIGH] Update wind correlation matrix to 2020-2026 period
- [MEDIUM] Validate flood loss cap methodology with actuarial team
- [LOW] Backfill missing coordinates using geocoding service
