| Markov Blanket of a node in a directed graph {MXM} | R Documentation |
Returns the Markov blanket of a node (or variable)
Description
Returns the Markov blanket of a node (or variable).
Usage
mb(G, node)
Arguments
G |
The graph matrix as produced from |
node |
A vector with one or more numbers indicating the seleted node(s) (or variable(s)). |
Details
This is a way to see the network for some given nodes. It is useful if you have many nodes and the whole network is a bit difficult to see clearly. Bear in mind that the values can be extracted with the $ symbol, i.e. this is an S3 class output.
Value
parents |
The parents of the node of interest. |
children |
The children of the node of interest. |
spouses |
The spouses of the node of interest. These are the other parents of the children of the node of interest. |
relatives |
Nodes which are connected with the node of interest, but it is not known whether they are parents or children. The edge between them is undirected. |
markov.blanket |
The Markov blanket of the node of interest. The collection of all the previous. |
