New Proximal Survival Bridge learning framework tackles censored outcomes

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Proximal Survival Bridge learning (PSB), a novel framework designed to estimate causal effects on time-to-event outcomes that are subject to right-censoring and unmeasured confounding. This flexible, doubly robust approach utilizes two distinct bridge learners: PSB-K, a kernel estimator, and PSB-N, a neural estimator. PSB has demonstrated strong performance across various benchmarks, including a standard SEM benchmark, a proximal semi-synthetic ACTG study, and the Framingham Heart Study, showing robustness even with weakened proxies or heavier censoring.

IMPACT Introduces a new statistical method for causal inference in survival analysis, potentially improving research in fields relying on time-to-event data.

    Flexible Doubly Robust Proximal Causal Inference for Censored Outcomes

    arXiv:2610.20893v1 Announce Type: cross Abstract: Estimating causal effects on right-censored time-to-event outcomes is challenging under unmeasured confounding. Proximal causal inference addresses unmeasured confounding through proxy variables, but existing proximal survival met…
