%description
Provides functions for handling missing data using Distributed Trimmed
Scores Regression and other imputation methods. It includes facilities for
data imputation, evaluation metrics, and clustering analysis. It is
designed to work in distributed computing environments to handle large
datasets efficiently. The philosophy of the package is described in Guo G.
(2024) <doi:10.1080/03610918.2022.2091779>.
