      public PopulationTetradTest(CorrelationMatrix CorrelationMatrix)

  • Method Details

    • getVarNames

      public String[] getVarNames()
      Specified by:
      getVarNames in interface TetradTest

    • getVariables

      public List<Node> getVariables()
      Specified by:
      getVariables in interface TetradTest

    • getDataSet

      public DataSet getDataSet()
      Specified by:
      getDataSet in interface TetradTest

    • tetradScore

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