gaussianVanishingIdeal(R)
gaussianVanishingIdeal computes the ideal in $R$ of homogeneous polynomial relations on the variancecovariance parameters of a graphical model on $G$ as explained in Chapter 3.3 of ``Lectures on Algebraic Statistics'' by Drton, Sturmfels, and Sullivant.




This method works for graphs, digraphs and mixed graphs without undirected edges.






This method currently works on really small examples because it computes the vanishing ideal as an elimination ideal.
The object gaussianVanishingIdeal is a method function with options.
