Optimized variance estimation under interference and complex experimental designs
Christopher Harshaw, Joel A. Middleton, Fredrik Sävje
Unbiased and consistent variance estimators generally do not exist for design-based treatment effect estimators because experimenters never observe more than one potential outcome…
The Power of Subsampling in Submodular Maximization
Christopher Harshaw, Ehsan Kazemi, Moran Feldman +1
We propose subsampling as a unified algorithmic technique for submodular maximization in centralized and online settings. The idea is simple: independently sample elements from the…
Design and Analysis of Bipartite Experiments under a Linear Exposure-Response Model
Christopher Harshaw, Fredrik Sävje, David Eisenstat +2
A bipartite experiment consists of one set of units being assigned treatments and another set of units for which we measure outcomes. The two sets of units are connected by a bipar…
