%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 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>.
