Provides a method of recovering the precision matrix for Gaussian graphical models efficiently. Our approach could be divided into three categories. First of all, we use Hard Graphical Thresholding for best subset selection problem of Gaussian graphical model, and the core concept of this method was proposed by Luo et al. (2014) <arXiv:1407.7819>. Secondly, a closed form solution for graphical lasso under acyclic graph structure is implemented in our package (Fattahi and Sojoudi (2019) <https://jmlr.org/papers/v20/17-501.html>). Furthermore, we implement block coordinate descent algorithm to efficiently solve the covariance selection problem (Dempster (1972) <doi:10.2307/2528966>). Our package is computationally efficient and can solve ultra-high-dimensional problems, e.g. p > 10,000, in a few minutes.

Install

R (CRAN)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("gif")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# one-time r2u setup for Ubuntu (noble)

curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash

# then install

sudo apt install r-cran-gif

Fast Ubuntu binaries via r2u (no compilation). Run the setup once per machine.

bspm (used by r2u) also needs make: sudo apt install make

sudo dnf copr enable iucar/cran

sudo dnf install R-CRAN-gif

RPMs from the iucar/cran COPR, rebuilt from CRAN.

sudo zypper install R-gif

RPMs auto-built from CRAN on openSUSE OBS.
