Project Spotlight

Health DKM on HRS Data

Health DKM turns complex longitudinal Health and Retirement Study (HRS) data into actionable system intelligence. Instead of static reporting, teams get decision-ready views of trajectory risk, transition pressure, and intervention timing.

What this solves

HRS-scale datasets are rich but difficult to operationalize. Health DKM resolves fragmented signal into interpretable state models and leverage points.

What teams get

A unified picture of risk trajectories, intervention windows, and model confidence that supports strategic, clinical, and program-level decisions.

Delivery model

Iterative briefs, reproducible artifacts, and practical implementation guidance for teams moving from exploratory analysis to operating decisions.

Toolset and output snapshots
