  • Method Details

    • indTestSubset

      IndependenceTest indTestSubset(List<Node> vars)
      Returns:
      an Independence test for a subset of the variables.

    • checkIndependence

      IndependenceResult checkIndependence(Node x, Node y, List<Node> z)
      Returns:
      true if the given independence question is judged true, false if not. The independence question is of the form x _||_ y | z, z = <z1,...,zn>, where x, y, z1,...,zn are variables in the list returned by getVariableNames().

    • checkIndependence

      default IndependenceResult checkIndependence(Node x, Node y, Node... z)
      Returns:
      true if the given independence question is judged true, false if not. The independence question is of the form x _||_ y | z, z = <z1,...,zn>, where x, y, z1,...,zn are variables in the list returned by getVariableNames().

    • getVariables

      List<Node> getVariables()
      Returns:
      the list of variables over which this independence checker is capable of determinining independence relations.

    • getVariable

      Node getVariable(String name)
      Returns:
      the variable by the given name.

    • getVariableNames

      List<String> getVariableNames()
      Returns:
      the list of names for the variables in getNodesInEvidence.

    • determines

      boolean determines(List<Node> z, Node y)
      Returns:
      true if y is determined the variable in z.

    • getAlpha

      double getAlpha()
      Returns:
      the significance level of the independence test.
      Throws:
      UnsupportedOperationException - if there is no significance level.

    • setAlpha

      void setAlpha(double alpha)
      Sets the significance level.

    • getData

      DataModel getData()
      Returns:
      The data model for the independence test.

    • getCov

      ICovarianceMatrix getCov()

    • getDataSets

      List<DataSet> getDataSets()

    • getSampleSize

      int getSampleSize()

    • getCovMatrices

      List<Matrix> getCovMatrices()

    • getScore

      double getScore()
      A score that is higher with more likely models.

    • setVerbose

      void setVerbose(boolean verbose)

    • isVerbose

      boolean isVerbose()

    • toString

      String toString()
      Overrides:
      toString in class Object
