Impact of correlation of predictors on discrimination of risk models in development and external populations

BACKGROUND: The area under the ROC curve (AUC) of risk models is known to be influenced by differences in case-mix and effect size of predictors. The impact of heterogeneity in correlation among predictors has however been under investigated. We sought to evaluate how correlation among predictors af...
