IndependenceResult

public IndependenceResult(IndependenceFact fact,
 boolean indep,
 double pValue,
 double score)

Constructor.

Parameters:

fact - The fact itself.

indep - The conditional independence result, true if the fact holds, false if not.

pValue - The p-values of the independence result, under the null (independence) hypothesis.

Method Details

serializableInstance

public static IndependenceResult serializableInstance()

Generates a simple exemplar of this class to test serialization.

• TetradSerializableUtils

getFact

public IndependenceFact getFact()

Returns the independence fact being stored.

Returns:

This fact

See Also:

• IndependenceFact

isIndependent

public boolean isIndependent()

Returns whether the fact holds--i.e., if the judgment is for independence.

Returns:

True if the fact holds, false if ot.

See Also:

• isDependent()

isDependent

public boolean isDependent()

Returns whether the fact fails to hold--i.e., if the judgment is for dependence. This is the negation of isIndependent.

Returns:

True if the fact does not, false if it does.

See Also:

• isIndependent()

getPValue

public double getPValue()

Returns the p-value of the fact under the null hypothesis of independence. A special case obtains if this fact is being used to store a d-separation fact, in which case the "p-value" is deemed to be 0 if the fact holds and 1 if it does not.

Returns:

The p-value of the result under the null hypothesis.

toString

public String toString()

Returns a string represnetation of this independence fact.

Overrides:

toString in class Object

Returns:

This string.

getScore

public double getScore()
