  • Method Details

    • localScore

      public double localScore(int i, int[] parents)
      Calculates the sample likelihood and BIC score for i given its parents in a simple SEM model
      Specified by:
      localScore in interface Score
      Parameters:
      i - The index of the node.
      parents - The indices of the node's parents.
      Returns:
      The score, or NaN if the score cannot be calculated.
