Replication package for “Direction-Indexed Negative-Control Bridging with Abstention under Hidden Confounding

This project looks at using “Direction‑Indexed Negative‑Control Bridging with Abstention under Hidden Confounding” for environmental‑engineering problems, especially air‑quality and photochemical smog modeling. Observational air‑pollution studies often hide confounding factors because they don’t measure some meteorological or spatial variables. The original paper’s replication package offers a statistical framework that tackles this issue. It combines negative‑control bridging with an abstention option that can be turned on when the hidden confounding is too strong to handle. We only have the replication‑package metadata; the full manuscript wasn’t examined. That means the exact mathematical proofs and the main empirical data sets are missing. Despite that, the replication package—containing analysis code, benchmark tools, and detailed protocols—provides

a solid base for M.Tech researchers. Students can use these statistical procedures to study causal links between smog precursors (like NOx and VOCs) and ambient ozone levels. The abstention feature helps make policy‑relevant environmental models more reliable when uncertainty is high.
