Constructor Details

SepsetsSet

public SepsetsSet(SepsetMap sepsets,
 IndependenceTest test)

Constructor for SepsetsSet.

Parameters:

sepsets - a SepsetMap object

test - a IndependenceTest object

Method Details

getSepset

public Set<Node> getSepset(Node a,
 Node b)

Retrieves the sepset between two nodes.

Specified by:

getSepset in interface SepsetProducer

Parameters:

a - the first node

b - the second node

Returns:

the set of nodes in the sepset between a and b

getSepsetContaining

public Set<Node> getSepsetContaining(Node a,
 Node b,
 Set<Node> s)

Retrieves the sepset for a and b, where we are expecting this sepset to contain all the nodes in s.

Specified by:

getSepsetContaining in interface SepsetProducer

Parameters:

a - the first node

b - the second node

s - the set of nodes to check in the sepset of a and b

Returns:

the set of nodes that the sepset of a and b is expected to contain.

Throws:

IllegalArgumentException - if the sepset of a and b does not contain all the nodes in s

getPValue

public double getPValue(Node a,
 Node b,
 Set<Node> sepset)

Description copied from interface: SepsetProducer

Specified by:

getPValue in interface SepsetProducer

Parameters:

a - the first node

b - the second node

sepset - the set of nodes

Returns:

the p-value for the statistical test

Throws:

UnsupportedOperationException - if this method is called
