The expected value of sample information calculations for external validation of risk prediction models
Mohsen Sadatsafavi, Andrew J Vickers, Tae Yoon Lee +2
In designing external validation studies of clinical prediction models, contemporary sample size calculation methods are based on the frequentist inferential paradigm. One of the w…
Minding non-collapsibility of odds ratios when recalibrating risk prediction models
Mohsen Sadatsafavi, Hamid Tavakoli, Abdollah Safari
In clinical prediction modeling, model updating refers to the practice of modifying a prediction model before it is used in a new setting. In the context of logistic regression for…
Uncertainty and Value of Information in Risk Prediction Modeling
Mohsen Sadatsafavi, Tae Yoon Lee, Paul Gustafson
Background: Due to the finite size of the development sample, predicted probabilities from a risk prediction model are inevitably uncertain. We apply Value of Information methodolo…
