In the spotlight: Machine learning unmasks group where interventions fail

Conditional average treatment effects (CATEs) allow researchers to study heterogeneous treatment effects, and Stata's new cate command provides the flexibility for fitting these models without parametric assumptions. In this spotlight, we demonstrate how using random forest to estimate CATEs can reveal effects missed by the parametric approach.
