Abbreviations: AUC, area under the receiver operating characteristic curve

^aEach ventile represents 5% of married couples in the sample ranked in terms of their predicted risk of marital violence

^bEstimates calculated from 20 replicates of 10-fold cross-validation of the final model

^cEstimates calculated from the final model

^dConcentration of risk refers to the percent of all observed occurrences of the outcome in a ventile or ventiles of the predicted risk distribution
