samplePair: Sample the parents of a pair of nodes (Gibbs sampler).

In rjbgoudie/structmcmc: Structural inference for Bayesian Networks and Variable Selection.

Description

Sample from posterior distribution on graph, conditional on all the edges, except for those corresponding to the parents sets of two nodes.

Usage

  samplePair(currentNetwork, numberOfNodes, nodesSeq,
    scoresParents, parentsTables, allRows, rowsThatContain)

Arguments

currentNetwork	A currentNetwork object
numberOfNodes	The number of nodes in the network. A numeric vector of length 1.
nodesSeq	The vector 1:nNodes(currentNetwork). (Supplied as an argument for possible speed gain)
scoresParents	A list of the form returned by scoreParentsTable()
parentsTables	A list of tables of the form returned by enumerateParentsTable()
allRows	The vector 1:nrow(parentsTables). (Supplied as an argument for possible speed gain)
rowsThatContain	A list of the form created by getRowsThatContain()

Value

Returns the sampled network. A currentNetwork object.
