Class LvDumb

java.lang.Object

edu.cmu.tetrad.search.LvDumb

All Implemented Interfaces:

IGraphSearch

public final class LvDumb
extends Object
implements IGraphSearch

LV-Dumb is a class that implements the IGraphSearch interface. The LV-Dumb algorithm finds the BOSS DAG for the dataset and then simply reports the PAG (Partially Ancestral Graph) structure of the BOSS DAG, without doing any further latent variable reasoning.

LvDumb

public LvDumb(Score score)

LV-Lite constructor. Initializes a new object of LvLite search algorithm with the given IndependenceTest and Score object.

Parameters:

score - The Score object to be used for scoring DAGs.

Throws:

NullPointerException - if score is null.

Method Details

search

public Graph search()
             throws InterruptedException

Run the search and return s a PAG.

Specified by:

search in interface IGraphSearch

Returns:

The PAG.

Throws:

InterruptedException - if any.

setKnowledge

public void setKnowledge(Knowledge knowledge)

Sets the knowledge used in search.

Parameters:

knowledge - This knowledge.

setVerbose

public void setVerbose(boolean verbose)

Sets the verbosity level of the search algorithm.

Parameters:

verbose - true to enable verbose mode, false to disable it

setNumStarts

public void setNumStarts(int numStarts)

Sets the number of starts for BOSS.

Parameters:

numStarts - The number of starts.

setUseDataOrder

public void setUseDataOrder(boolean useDataOrder)

Sets whether the search algorithm should use the order of the data set during the search.

Parameters:

useDataOrder - true if the algorithm should use the data order, false otherwise

setUseBes

public void setUseBes(boolean useBes)

Sets whether to use the BES (Backward Elimination Search) algorithm during the search.

Parameters:

useBes - true to use the BES algorithm, false otherwise
