Robustly fitting Gaussian graphical models: the R-package robFitConGraph

英文摘要：

A tutorial-style introduction to the R-package robFitConGraph is given. The latter provides a robust goodness-of-fit test for Gaussian graphical models. Its use is demonstrated at a data example on music performance anxiety, which also illustrates why one would want to fit a Gaussian graphical model - and why one should do so robustly. The underlying statistical theory is briefly explained. The paper describes package version 0.4.1, available on CRAN from December 1, 2022. See https://CRAN.R-project.org/package=robFitConGraph
