Class IndTestMnlrLr

java.lang.Object
edu.cmu.tetrad.search.work_in_progress.IndTestMnlrLr
All Implemented Interfaces:
IndependenceTest

public class IndTestMnlrLr extends Object implements IndependenceTest
Performs a test of conditional independence X _||_ Y | Z1...Zn where all searchVariables are either continuous or discrete. This test is valid for both ordinal and non-ordinal discrete searchVariables.

  • Method Details

    • indTestSubset

      public IndependenceTest indTestSubset(List<Node> vars)
      Description copied from interface: IndependenceTest
      Returns an Independence test for a sublist of the variables.
      Specified by:
      indTestSubset in interface IndependenceTest
      Parameters:
      vars - The sublist of variables.
      Returns:
      an Independence test for a subset of the searchVariables.
    • checkIndependence

      public IndependenceResult checkIndependence(Node x, Node y, Set<Node> _z)
      Specified by:
      checkIndependence in interface IndependenceTest
      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 searchVariables in the list returned by getVariableNames().

      Specified by:
      getVariables in interface IndependenceTest
      Returns:
      the list of searchVariables over which this independence checker is capable of determinining independence relations.
    • determines

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

      Throws:
      UnsupportedOperationException - if there is no significance level.
    • setAlpha

      public void setAlpha(double alpha)
      Sets the significance level.
      Specified by:
      setAlpha in interface IndependenceTest

      Returns:
      True is so.
    • setVerbose

      public void setVerbose(boolean verbose)
      Sets whether this test will print verbose output.
      Specified by:
