Description: Provides methods to evaluate predictive performance of models that 
    estimate risks under hypothetical intervention scenarios 
    (interventional/causal/counterfactual predictions) with observational data 
    subject to treatment-outcome confounding. Inverse probability of treatment 
    weighting (IPTW) is used to construct a pseudopopulation in which all 
    individuals receive a specified intervention, enabling assessment of 
    agreement between predicted risks under the intervention and observed 
    outcomes in the pseudo-population corresponding to that intervention. 
    Package supports binary and time-to-event outcomes under binary 
    interventions made at a single time point. Performance measures supported 
    are AUC (Area Under the receiving operating characteristic Curve), Brier 
    score, observed-expected ratio, and calibration plots. Methods implemented 
    in this package are based on work by Keogh and Van Geloven (2024) 
    <DOI:10.1097/EDE.0000000000001713>.
