Description: Fit linear, logistic and Cox models regularized with L0, lasso
    (L1), elastic-net (L1 and L2), or net (L1 and Laplacian) penalty, and
    their adaptive forms, such as adaptive lasso / elastic-net and net
    adjusting for signs of linked coefficients. It solves the L0 penalty
    problem by simultaneously selecting regularization parameters and
    performing hard-thresholding or selecting the number of non-zeros. This
    augmented and penalized minimization method provides an approximation
    solution to the L0 penalty problem, but runs as fast as L1 regularization.
    The package uses a one-step coordinate descent algorithm and runs extremely
    fast by taking into account the sparsity structure of coefficients. It can
    handle very high dimensional data and has superior selection performance.
