GGMselect-package {GGMselect} | R Documentation |
GGMselect is a package dedicated to graph estimation in Gaussian Graphical Models. The main functions return the adjacency matrix of an undirected graph estimated from a data matrix.
This package is developed in the Applied Mathematics and Informatics (http://www.jouy.inra.fr/mia_eng/) Lab of INRA - Jouy-en-Josas, France.
