Abstract:
|
New research related to a novel sampling method for estimating causal effects from alternative rankings will be introduced. The ability to draw inferences is challenged by the presence of graph-based interference across units that violates SUTVA and specifically produces zero pairwise inclusion probabilities. Attempts to produce conservative variance estimates are explored through simulations along with a review of related literature and recent contributions.
