Constructor Details

DagToPag

public DagToPag(Graph dag)

Constructs a new FCI search for the given independence test and background knowledge.

Parameters:

dag - a Graph object

Method Details

calcAdjacencyGraph

public static Graph calcAdjacencyGraph(Graph dag)

Calculates the adjacency graph for the given Directed Acyclic Graph (DAG).

Parameters:

dag - The input Directed Acyclic Graph (DAG).

Returns:

The adjacency graph represented by a Graph object.

convert

public Graph convert()

This method does the conversion of DAG to PAG.

Returns:

Returns the converted PAG.

getFinalStrategyUsingDsep

public static R0R4StrategyTestBased getFinalStrategyUsingDsep(Graph mag,
 Graph pag,
 Knowledge knowledge,
 boolean verbose)

getKnowledge

public Knowledge getKnowledge()

Getter for the field knowledge.

Returns:

a Knowledge object

setKnowledge

public void setKnowledge(Knowledge knowledge)

Setter for the field knowledge.

Parameters:

knowledge - a Knowledge object

isCompleteRuleSetUsed

public boolean isCompleteRuleSetUsed()

isCompleteRuleSetUsed.

Returns:

true if Zhang's complete rule set should be used, false if only R1-R4 (the rule set of the original FCI) should be used. False by default.

setCompleteRuleSetUsed

public void setCompleteRuleSetUsed(boolean completeRuleSetUsed)

Setter for the field completeRuleSetUsed.

Parameters:

completeRuleSetUsed - set to true if Zhang's complete rule set should be used, false if only R1-R4 (the rule set of the original FCI) should be used. False by default.

setVerbose

public void setVerbose(boolean verbose)

Setws whether verbose output should be printed.

Parameters:

verbose - True, if so.
