  • Constructor Details

    • IndTestRegression

      public IndTestRegression(DataSet dataSet, double alpha)
      Deprecated.
      Constructs a new Independence test which checks independence facts based on the correlation matrix implied by the given data set (must be continuous). The given significance level is used.
      Parameters:
      dataSet - A data set containing only continuous columns.
      alpha - The alpha level of the test.

    • indTestSubset

      public IndependenceTest indTestSubset(List<Node> vars)
      Deprecated.
      Performs an independence test for a sublist of variables.
      Specified by:
      indTestSubset in interface IndependenceTest
      Parameters:
      vars - The sublist of variables.
      Returns:
      The independence test result.

    • checkIndependence

      public IndependenceResult checkIndependence(Node xVar, Node yVar, Set<Node> zList)
      Deprecated.
      Checks the independence between two variables, given a set of conditioning variables.
      Specified by:
      checkIndependence in interface IndependenceTest
      Parameters:
      xVar - The first variable to test for independence.
      yVar - The second variable to test for independence.
      zList - The set of conditioning variables.
      Returns:
      An IndependenceResult object containing the result of the independence test.

    • getAlpha

      public double getAlpha()
      Deprecated.
      Gets the getModel significance level.
      Specified by:
      getAlpha in interface IndependenceTest
      Returns:
      a double

    • setAlpha

      public void setAlpha(double alpha)
      Deprecated.
      Sets the significance level.
      Specified by:
      setAlpha in interface IndependenceTest
      Parameters:
      alpha - This level.
      Throws:
      IllegalArgumentException - if alpha is not within the range [0, 1].

      Deprecated.
      Returns the list of variables associated with this object.
      Specified by:
      getVariables in interface IndependenceTest
      Returns:
      the list of variables

    • toString

      public String toString()
      Deprecated.
      Returns a string representation of the Linear Regression Test object.
      Specified by:
      toString in interface IndependenceTest
      Overrides:
