Causal Inference without Balance Checking: Coarsened Exact Matching
Causal Inference without Balance Checking: Coarsened Exact Matching
We discuss a method for improving causal inferences called “Coarsened Exact Matching” (CEM), and the new “Monotonic Imbalance Bounding” (MIB) class of matching methods from which CEM is derived. We summarize what is known about CEM and MIB, derive and illustrate several new desirable statistical properties of CEM, and then …
