%description
Component-wise gradient boosting for analysis of multiply imputed
datasets. Implements the algorithm Boosting after Multiple Imputation
(MIBoost), which enforces uniform variable selection across imputations
and provides utilities for pooling. Includes a cross-validation workflow
that first splits the data into training and validation sets and then
performs imputation on the training data, applying the learned imputation
models to the validation data to avoid information leakage. Supports
Gaussian and logistic loss. Methods relate to gradient boosting and
multiple imputation as in Buehlmann and Hothorn (2007)
