Transport G-Computation: A Distributional Approach to Longitudinal Causal Inference via Optimal Transport

This paper proposes Transport G-Computation (TGC), a novel distributional framework combining longitudinal g-computation with optimal transport to estimate Wasserstein causal effects, which demonstrates superior performance over parametric g-computation in scenarios involving confounded feedback and model misspecification despite higher computational costs.

Inference for the Lorenz Curve and Gini Index under the Geometric Distribution

This paper establishes the exact and asymptotic distributional properties of maximum likelihood estimators for the Lorenz curve and Gini index under the geometric distribution, providing a rigorous inferential framework for inequality measures in discrete settings through closed-form derivations, consistency proofs, simulation studies, and real-data application.

Efficient recursive data snooping for correlated observations

This paper introduces Efficient Recursive Data Snooping (ERDS), an exact recursive reformulation of iterative data snooping that significantly reduces computational costs for correlated observations by replacing repeated model re-decompositions with closed-form updates, achieving a 96.5% runtime reduction in GNSS data processing while maintaining identical detection results to classical methods.

Machine Learning Analysis of Socioeconomic Stratification and Health Vulnerability in the United States

Using a supervised machine learning pipeline on a synthetic dataset calibrated to US national surveys, this study demonstrates that structural socioeconomic factors, particularly education and occupational class, are the dominant predictors of health vulnerability—explaining 82% of feature importance and supporting fundamental cause theory over behavioral explanations.
