Modeling Covariate Transition for Efficient Estimation of Longitudinal Treatment Effects in Randomized Experiments
arXiv:2605.31443v1 Announce Type: cross Abstract: We present a regression-adjustment framework designed for the estimation of longitudinal treatment effects in randomized experiments under static regimes. While regression-adjustment methods are useful for variance reduction in randomized experiments by using pre-treatment covariates, they usually focus only on average effects, from which we cannot obtain valuable insights into when the effects appear and how long they continue. To address this issue, we consider intermediate outcomes and evolving post-treatment covariates over time, and we rep
The increasing complexity of AI models and the demand for more nuanced understanding of dynamic causal effects in real-world applications drive the need for advanced statistical frameworks like this.
Improved methods for estimating longitudinal treatment effects can lead to more effective policy interventions, drug development, and personalized AI applications by precisely identifying when and how effects manifest over time.
This research provides a more sophisticated approach to understanding causality in dynamic systems, moving beyond simple average treatment effects to assess time-varying impacts of interventions.
