%description
Provides implementations of a family of Lasso variants, including Dantzig
Selector, LAD Lasso, SQRT Lasso, and Lq Lasso, for estimating
high-dimensional sparse linear models. We adopt the alternating direction
method of multipliers and convert the original optimization problem into a
sequence of L1-penalized least-squares minimization problems that are
efficiently solved by linearization and multi-stage screening. In addition
to sparse linear model estimation, we provide extensions of these methods
to sparse Gaussian graphical model estimation, including TIGER and CLIME,
using either L1 or adaptive penalties. Missing values can be tolerated for
Dantzig selector and CLIME. Computation is memory-optimized using sparse
matrix output. For more information, see
<https://www.jmlr.org/papers/volume16/li15a/li15a.pdf>.
