Optimal estimation of generalized causal effects in cluster-randomized trials with multiple outcomes
Xinyuan Chen, Fan Li
Cluster-randomized trials (CRTs) are widely used to evaluate group-level interventions and increasingly collect multiple outcomes capturing complementary dimensions of benefit and…
