  • Constructor Details

    • TetradTestPopulation

      public TetradTestPopulation(CorrelationMatrix CorrelationMatrix)

      Constructor for TetradTestPopulation.

      Parameters:
      CorrelationMatrix - a CorrelationMatrix object

  • Method Details

    • getVarNames

      public String[] getVarNames()

      getVarNames.

      Specified by:
      getVarNames in interface TetradTest
      Returns:
      an array of String objects

    • getVariables

      public List<Node> getVariables()

      getVariables.

      Specified by:
      getVariables in interface TetradTest
      Returns:
      a List object

    • getDataSet

      public DataSet getDataSet()

      getDataSet.

      Specified by:
      getDataSet in interface TetradTest
      Returns:
      a DataSet object

    • tetradScore

      public int tetradScore(int v1, int v2, int v3, int v4)

      tetradScore.

      Population scores: assumes CorrelationMatrix is the population covariance CorrelationMatrix. Due to numerical rounding problems, we need a parameter epsilon to control it. Nothing here is implemented for discrete data (yet).

      tetradScore in interface TetradTest
      Parameters:
      v1 - a int
      v2 - a int
      v3 - a int
      v4 - a int
      Returns:
      a int
