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. Supports interventions with
        binary or categorical treatment levels, applied either at a
        single time point or as longitudinal treatment strategies with
        sequential treatment decisions. 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)
