arXiv:2606.01539v1 Announce Type: cross Abstract: Estimating the causal effect of time-varying treatments on survival outcomes in large observational studies is computationally demanding, particularly when outcomes are rare. While g-formula-based methods such as the iterative conditional expectation (ICE) estimator provide a principled framework for longitudinal causal inference, they become computationally expensive, especially when bootstrap-based variance estimation is required. In addition, outcome rarity at each time point induces severe class imbalance, leading to instability and converg
The increasing scale and complexity of observational health data, coupled with rising demand for precise causal inference in AI medical applications, necessitates more efficient computational methods for rare events. Advances in machine learning are making such methods more feasible.
This development allows for more accurate and computationally feasible causal inference in large datasets, particularly for critical rare events, which can improve treatment effect estimation and AI-driven clinical decision-making. It addresses a significant bottleneck in applying advanced analytical methods to real-world health outcomes.
The computational burden of estimating causal effects for rare events in large longitudinal datasets will be significantly reduced, making complex analyses more accessible and reliable for researchers and AI systems. This could lead to faster and more robust discovery of causal links in medicine.
