Description: 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.
