New framework tackles predictive inference with missing data

Researchers have developed a new framework for predictive inference that handles coarsened or missing data in training and calibration sets. The proposed methods, Robust Split Prediction (RSP) and Robust Split Conformal Prediction (RSCP), combine semiparametric theory with conformal methods to provide formal coverage guarantees. These techniques are applicable to various missingness patterns, including multi-stage monotone and non-monotone scenarios, and have been demonstrated through simulations and a real-world application in rheumatoid arthritis research.
