Value of Information Analysis for External Validation of Risk Prediction Models
Mohsen Sadatsafavi, Tae Yoon Lee, Laure Wynants +2
Background: Before being used to inform patient care, a risk prediction model needs to be validated in a representative sample from the target population. The finite size of the va…
Methodological concerns about 'concordance-statistic for benefit' as a measure of discrimination in treatment benefit prediction
Yuan Xia, Paul Gustafson, Mohsen Sadatsafavi
Prediction algorithms that quantify the expected benefit of a given treatment conditional on patient characteristics can critically inform medical decisions. Quantifying the perfor…
Closed-Form Solution of the Unit Normal Loss Integral in Two-Dimensions
Tae Yoon Lee, Paul Gustafson, Mohsen Sadatsafavi
In Value of Information (VoI) analysis, the unit normal loss integral (UNLI) frequently emerges as a solution for the computation of various VoI metrics. However, one limitation of…
Programmable Interface for Statistical & Simulation Models (PRISM): Towards Greater Accessibility of Clinical and Healthcare Decision Models
Amin Adibi, Stephanie Harvard, Mohsen Sadatsafavi
Background: Increasingly, decision-making in healthcare relies on computer models, be it clinical prediction models at point of care or decision-analytic models at the policymaking…
