  • Method Details

    • getSepset

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

      getSepset.

      Parameters:
      a - a Node object
      b - a Node object
      Returns:
      a Set object

    • getSepsetContaining

      Set<Node> getSepsetContaining(Node a, Node b, Set<Node> s)
      Returns the subset for a and b, where this sepset is expected to contain all the nodes in s. The behavior is morphed depending on whether sepsets are calculated using an independence test or not. If sepsets are calculated using an independence test, and a sepset is not found containing all the nodes in s, then the method will return null. Otherwise, if the discovered sepset does not contain all the nodes in s, the method will throw an exception.
      Parameters:
      a - the first node
      b - the second node
      s - the set of nodes
      Returns:
      the set of nodes that sepsets for a and b are expected to contain.

      Returns:
      the p-value for the statistical test
