+### Policy Learning
+
+You can also perform direct policy learning from observational data, using the doubly robust method for offline
+policy learning. These methods directly predict a recommended treatment, without internally fitting an explicit
+model of the conditional average treatment effect.

+from econml.policy import DRPolicyTree, DRPolicyForest
