public class Dm
extends AbstractBootstrapAlgorithm
implements Algorithm, AcceptsKnowledge, ReturnsBootstrapGraphs, TakesIndependenceWrapper

Algorithm-comparison wrapper for the Murray-Watters/Glymour style Detect-Mimic search, DM.

This wrapper builds the requested independence test from the supplied IndependenceWrapper, runs Dm, and returns the resulting graph.

The underlying DM search internally performs both a depth-0 PC run and a full-depth PC run as part of the Murray-Watters/Glymour procedure. Accordingly, no external PC-depth parameter is exposed here.

Constructor Details

Dm

public Dm()

Constructs the algorithm with a default Fisher Z test.

Dm

public Dm(IndependenceWrapper test)

Constructs the algorithm with the supplied independence wrapper.

Parameters:

test - the independence wrapper

Method Details

getComparisonGraph

public Graph getComparisonGraph(Graph graph)

Returns the comparison graph for the supplied graph.

As with other CPDAG-style wrappers, the comparison graph is the CPDAG of the DAG obtained from the input graph.

Specified by:

getComparisonGraph in interface Algorithm

Parameters:

graph - the graph

Returns:

the comparison graph

getDescription

public String getDescription()

Returns a description of this algorithm.

Specified by:

getDescription in interface Algorithm

Returns:

the description

getDataType

public DataType getDataType()

Returns the data type supported by the underlying test.

Specified by:

getDataType in interface Algorithm

Returns:

the data type

getParameters

public List<String> getParameters()

Returns the list of parameters used by this algorithm.

Specified by:

getParameters in interface HasParameters

Returns:

the parameter names

getKnowledge

public Knowledge getKnowledge()

Returns the background knowledge.

Specified by:

getKnowledge in interface AcceptsKnowledge

Returns:

the background knowledge

setKnowledge

public void setKnowledge(Knowledge knowledge)

Sets the background knowledge.

Specified by:

setKnowledge in interface AcceptsKnowledge

Parameters:

knowledge - the background knowledge

getIndependenceWrapper

public IndependenceWrapper getIndependenceWrapper()

Description copied from interface: TakesIndependenceWrapper

Returns the independence wrapper.

Specified by:

getIndependenceWrapper in interface TakesIndependenceWrapper

Returns:

the independence wrapper.

setIndependenceWrapper

public void setIndependenceWrapper(IndependenceWrapper independenceWrapper)

Description copied from interface: TakesIndependenceWrapper

Sets the independence wrapper.

Specified by:

setIndependenceWrapper in interface TakesIndependenceWrapper

Parameters:

independenceWrapper - the independence wrapper.
