graphpcor: correlation from nodes and edges

Description

A graphpcor is a graph where a node represents a variable and an edge represent a conditional distribution. The correlation built from a graphpcor consider the parameters for the Cholesky of a precision matrix, whose non-zero pattern is given from the graph.

Methods (by class)

• graphpcor(list): Each element may be a character or formula.

• graphpcor(formula): Each term represents a node, and each ~ an edge.

• graphpcor(character): Each term represents a node, and each ~ an edge.

• graphpcor(matrix): Build a graphpcor from a matrix object

• graphpcor(Matrix): Build a graphpcor for a Matrix object

Methods (by generic)

• Laplacian(graphpcor): The Laplacian method for a graphpcor

• print(graphpcor): The print method for graphpcor

• summary(graphpcor): The summary method for graphpcor

• dim(graphpcor): The dim method for graphpcor

• plot(graphpcor): The plot method for a graphpcor

• vcov(graphpcor): The vcov method for a graphpcor

• prec(graphpcor): The precision method for 'graphpcor'

• cgeneric(graphpcor): The cgeneric method for graphpcor uses cgeneric_graphpcor()

Functions

• cgeneric(Matrix): The cgeneric method for Matrix uses cgeneric_graphpcor()
