Important Notations in the Design of Cluster Experiments Under Network Interference

TLDR

Unlock the potential of causal clustering with practical recommendations from Davide Viviano and team. Understand how to choose the optimal adjacency matrix based on prior knowledge, decide between cluster or Bernoulli design with a rule of thumb, and implement optimal clusters using a straightforward algorithm. A comprehensive guide for researchers aiming for precision in their experimental designs.via the TL;DR App
