%description
Multiple imputation using 'XGBoost', subsampling, and predictive mean
matching as described in Deng and Lumley (2023)
<doi:10.1080/10618600.2023.2252501>.  The package supports various types
of variables, offers flexible settings, and enables saving an imputation
model to impute new data. Data processing and memory usage have been
optimised to speed up the imputation process.
