These are the recurring questions that shape the firm’s work and future publications. The emphasis is on methods that make important analysis easier to understand, test, and use.
Operational databases change. Historical snapshots create a stable record for reporting, regulation, model validation, and later review.
Data, assumptions, controls, interfaces, scenarios, review steps, and documentation turn a model into a dependable forecasting system.
Conflicting reports often arise from differences in populations, timing, denominators, exclusions, or source systems.
Percentages based on different populations cannot always be added or compared directly. Definitions matter.
Both require careful data handling, visible assumptions, reproducible calculations, clear documentation, and results that can withstand close review.
Trace inputs, check formulas, test assumptions, reproduce outputs, and determine whether the model is suitable for an important decision.
Preserve valuable subject-matter knowledge while improving control, repeatability, scenario management, and documentation.
AI can speed up coding, debugging, documentation, and research. Analytical judgment still determines what to ask and whether the result makes sense.
