Description: Provides a unified framework for sparse-group precision matrix
    estimation in Gaussian graphical models using combined element-wise and
    group-wise regularization. It supports multiple sparse-group penalties,
    including lasso, adaptive lasso, and several non-convex penalties such as
    SCAD and MCP. Non-convex estimates can be computed using one-step or
    iterative LLA, with weighted subproblems solved efficiently using ADMM-based
    optimization. The package is designed for high-dimensional network inference
    where both sparsity and group structure are present.
