Accuracy of Claims-Based Risk Scoring Models

The Society of Actuaries is pleased to make available research material that presents the results of a study comparing health risk scoring models. The study builds on prior SOA studies with a similar objective. The material was authored by Geof Hileman and Spenser Steele.

If you have comments or questions, please contact Steve Siegel, Research Actuary at ssiegel@soa.org.

As of 10/28/16, the report was updated to reflect a change in results for the CRG model in figures 4.2.3 and 4.2.4.

Note: The Society of Actuaries does not endorse, explicitly or implicitly for any purposes, software packages evaluated in the study.
