gaussianRing(...,lVariableName=>...) -- symbol used for indeterminates in a ring of Gaussian joint probability distributions

Usage:

gaussianRing(G,lVariableName=>w)
Inputs:
- w, a Symbol or a String

Description

The option gaussianRing(G,lVariableName=>w) changes the symbol used for intedeterminates in the regression matrix in a polynomial ring created with gaussianRing.

i1 : G = mixedGraph(digraph {{b,{c,d}},{c,{d}}},bigraph {{a,d}})

o1 = MixedGraph{Bigraph => Bigraph{a => {d}}   }
                                   d => {a}
                Digraph => Digraph{b => {c, d}}
                                   c => {d}
                                   d => {}
                Graph => Graph{}
