%description
A classification tree method that uses Uncorrelated Linear Discriminant
Analysis (ULDA) for variable selection, split determination, and model
fitting in terminal nodes.  It automatically handles missing values and
offers visualization tools. For more details, see Wang (2024)
<doi:10.48550/arXiv.2410.23147>.
