%description
Multiple imputation using 'XGBoost', subsampling, and predictive mean
matching as described in Deng and Lumley (2023) <arXiv:2106.01574>. Our
method utilizes the capabilities of XGBoost, a highly efficient
implementation of gradient boosted trees, to capture interactions and
non-linear relations automatically. Moreover, we have integrated
subsampling and predictive mean matching to minimize bias and reflect
appropriate imputation variability. This package supports various types of
variables and offers flexible settings for subsampling and predictive mean
matching. Additionally, it includes diagnostic tools for evaluating the
quality of the imputed values.
