Researchers have developed a new augmented transfer regression learning method to address situations where crucial covariates are entirely missing in a target population, a common issue with large datasets like the UK Biobank. This technique is designed for cross-population missing data problems, assuming that while the relationship between outcomes and observed variables might change between populations, the conditional distribution of missing covariates remains constant. The proposed estimator is doubly robust and achieves semiparametric efficiency under specific conditions. AI
