Summary

A new large-scale benchmark has been developed for counterfactual prediction in epidemic time series, specifically designed to address the current lack of realistic datasets with observable counterfactual outcomes. This benchmark supports both static and time-varying treatments, alongside single-policy and multi-policy intervention settings, enabling comprehensive evaluation of causal inference methods. It is generated by leveraging a calibrated agent-based model, which integrates real-world demographic, mobility, epidemiological, and policy data to produce realistic counterfactual trajectories across more than 150 U.S. counties. Initial evaluations using this benchmark demonstrate substantial performance differences among various causal inference techniques, highlighting the inherent challenges in accurate time-series causal reasoning.

Key takeaway

For research scientists developing or evaluating causal inference methods, this new benchmark offers a critical tool to assess model performance against realistic epidemic scenarios. Your current models might show substantial performance differences when tested with time-varying interventions and multi-policy settings. Utilize this benchmark to validate your approaches, ensuring they generalize effectively beyond simplified simulations and address the complexities of real-world causal reasoning.
