%description
Check the irrepresentable condition (IRC) in both L1-regularized
regression <doi:10.1109/TIT.2006.883611> and Gaussian graphical models.
The IRC requires that the important and unimportant variables are not
correlated, at least not all that much, and it is necessary for consistent
model selection. Exploring the IRC as a function of the number of
variables, assumed sparsity, and effect size can provide valuable insights
into the model selection properties of L1-regularization.
