BDgraph (version 2.43)

select: Graph selection

Description

Provides the selected graph which, based on input, could be a graph with links for which their estimated posterior probabilities are greater than 0.5 (default) or a graph with the highest posterior probability; see examples.

Usage

select( bdgraph.obj, cut = NULL, vis = FALSE )

Arguments

bdgraph.obj

An object of S3 class "bdgraph", from function bdgraph.

cut

Threshold for including the links in the selected graph based on the estimated posterior probabilities of the links; see the examples.

vis

Visualize the selected graph structure.

Value

G

An adjacency matrix corresponding to the selected graph.
