Constructor Details

TetradTestPopulation

public TetradTestPopulation(CorrelationMatrix CorrelationMatrix)

Constructor for TetradTestPopulation.

Parameters:

CorrelationMatrix - a CorrelationMatrix object

Method Details

getVarNames

public String[] getVarNames()

getVarNames.

Specified by:

getVarNames in interface TetradTest

Returns:

an array of String objects

getVariables

public List<Node> getVariables()

getVariables.

Specified by:

getVariables in interface TetradTest

Returns:

a List object

getDataSet

public DataSet getDataSet()

getDataSet.

Specified by:

getDataSet in interface TetradTest

Returns:

a DataSet object

tetradScore

public int tetradScore(int v1,
 int v2,
 int v3,
 int v4)

tetradScore.

Population scores: assumes CorrelationMatrix is the population covariance CorrelationMatrix. Due to numerical rounding problems, we need a parameter epsilon to control it. Nothing here is implemented for discrete data (yet).

Specified by:

tetradScore in interface TetradTest

Parameters:

v1 - a int

v2 - a int

v3 - a int

v4 - a int

Returns:

a int

tetradScore3

public boolean tetradScore3(int v1,
 int v2,
 int v3,
 int v4)

tetradScore3.

Specified by:

tetradScore3 in interface TetradTest

Parameters:

v1 - a int

v2 - a int

v3 - a int

v4 - a int

Returns:

a boolean

tetradScore1

public boolean tetradScore1(int v1,
 int v2,
 int v3,
 int v4)

tetradScore1.

Specified by:

tetradScore1 in interface TetradTest

Parameters:

v1 - a int

v2 - a int

v3 - a int

v4 - a int

Returns:

a boolean

tetradHolds

public boolean tetradHolds(int v1,
 int v2,
 int v3,
 int v4)

tetradHolds.

Specified by:
