研究人员开发了一种新的增强迁移回归学习方法，以解决目标人群中关键协变量完全缺失的情况，这是UK Biobank等大型数据集中常见的问题。该技术专为跨人群缺失数据问题设计，假设虽然结果与观测变量之间的关系在不同人群中可能发生变化，但缺失协变量的条件分布保持不变。所提出的估计量是双重稳健的，并在特定条件下实现了半参数效率。 AI
影响 引入了一种处理大规模数据集中缺失数据的新颖统计方法，有可能提高基因组学和流行病学等领域的分析准确性。

Large-scale population-level datasets, such as the UK Biobank and the All of Us Research Program, often lack covariates needed for a specific analysis, such as genetic or lifestyle measures, while related studies measure them. This creates a cross-population missing data problem …
