Confidence Intervals for Rate Estimation with Importance Sampling in Autonomous Vehicle Evaluation
Aiyou Chen, Ruixuan Rachel Zhou, Joseph J. Lee +2
Accounting for both rare events and complex sampling presents challenges when quantifying uncertainty for rate estimation in autonomous vehicle performance evaluation. In this pape…
Behavioral event detection and rate estimation for autonomous vehicle evaluation
Maria A. Terres, Aiyou Chen, Ruixuan Rachel Zhou +1
Autonomous vehicles are continually increasing their presence on public roads. However, before any new autonomous driving software can be approved, it must first undergo a rigorous…
Supergeo Design: Generalized Matching for Geographic Experiments
Aiyou Chen, Nick Doudchenko, Shunhua Jiang +2
We propose a generalization of the standard matched pairs design in which experimental units (often geographic regions or geos) may be combined into larger units/regions called "su…
Semiparametric Estimation of Treatment Effects in Randomized Experiments
Susan Athey, Peter J. Bickel, Aiyou Chen +2
We develop new semiparametric methods for estimating treatment effects. We focus on settings where the outcome distributions may be thick tailed, where treatment effects may be sma…
Trimmed Match Design for Randomized Paired Geo Experiments
Aiyou Chen, Marco Longfils, Nicolas Remy
How to measure the incremental Return On Ad Spend (iROAS) is a fundamental problem for the online advertising industry. A standard modern tool is to run randomized geo experiments,…
Robust Causal Inference for Incremental Return on Ad Spend with Randomized Paired Geo Experiments
Aiyou Chen, Timothy C. Au
Evaluating the incremental return on ad spend (iROAS) of a prospective online marketing strategy (i.e., the ratio of the strategy's causal effect on some response metric of interes…
