Independent validation for trusted models
Arocha & Associates GmbH provides independent model validation services across actuarial, financial, and machine learning applications. We ensure that models are conceptually sound, correctly implemented, and performing as intended under regulatory and governance expectations.
Our approach combines actuarial knowledge, statistical testing, and practical interpretation — offering confidence that models support reliable and transparent decision-making.
Our Support Includes
Actuarial Model Review
We assess reserving, pricing, and capital models for methodological soundness, assumptions, and parameter consistency, ensuring they reflect business realities and regulatory requirements.
Machine Learning Validation
We perform quantitative back-testing and qualitative assessments of data-driven models, reviewing explainability, bias, and performance stability for governance and model risk management purposes.
Implementation Verification
Our experts compare theoretical designs with production code and outputs, verifying reproducibility, documentation, and control processes across teams and systems.

We assist clients in establishing robust model governance frameworks, including validation policies, version control, and escalation mechanisms. Our work supports compliance with internal model governance under Solvency II, IFRS 17, and related frameworks.
