-A package for policy evaluation using generalized Qini curves. Evaluate data-driven treatment targeting rules for one or more treatment arms over different budget constraints. The policy values can be estimated in both experimental or observational settings under unconfoundedness using either inverse-propensity weighting or doubly robust methods.
