Goodness-of-Fit Tests for High-Dimensional Gaussian Graphical Models via Exchangeable Sampling
Xiaotong Lin, Weihao Li, Fangqiao Tian +1
We introduce a general framework for testing goodness-of-fit for Gaussian graphical models in both the low- and high-dimensional settings. This framework is based on a novel algori…
