Description Details Author(s) References


This package solves the primal formulation of the Graphical Lasso problem, by solving the duals (box QPs) of the block problems.

The outer block-wise optimization routine is written in R with the inner QP solver written in Fortran with a R wrapper around it.


Package: dpglasso
Type: Package
Version: 1.0

There are two functions dpglasso and box_qp_f.

The function dpglasso solves the primal formulation of the Graphical Lasso. The function box_qp_f solves a box constrained Quadratic program via cyclical coordinate descent.
