Statistical inference using debiased group graphical lasso for multiple sparse precision matrices
Sayan Ranjan Bhowal, Debashis Paul, Gopal K Basak +1
Debiasing group graphical lasso estimates enables statistical inference when multiple Gaussian graphical models share a common sparsity pattern. We analyze the estimation propertie…
