title: 'hierNest: Penalized Regression with Hierarchical Nested Parameterization Structure'
version: 1.0.2
doi: 10.32614/CRAN.package.hierNest
abstract: Efficient implementation of penalized regression with hierarchical nested
  parametrization for grouped data. The package provides penalized regression methods
  that decompose subgroup specific effects into shared global effects, Major subgroup
  specific effects, and Minor subgroup specific effects, enabling structured borrowing
  of information across related clinical subgroups. Both lasso and hierarchical overlapping
  group lasso penalties are supported to encourage sparsity while respecting the nested
  subgroup structure. Efficient computation is achieved through a modified design
  matrix representation and a custom majorization minimization algorithm for overlapping
  group penalties.
