%description
Implementation of the tree-guided feature selection and logic aggregation
approach introduced in Chen et al. (2024)
<doi:10.1080/01621459.2024.2326621>. The method enables the selection and
aggregation of large-scale rare binary features with a known hierarchical
structure using a convex, linearly-constrained regularized regression
framework. The package facilitates the application of this method to both
linear regression and binary classification problems by solving the
optimization problem via the smoothing proximal gradient descent algorithm
(Chen et al. (2012) <doi:10.1214/11-AOAS514>).
