    • localScore

      public double localScore(int y, int[] z)
      Calculates the sample likelihood and BIC score for y given its z in a simple SEM model

      Parameters:
      y - The index of the node.
      z - The indices of the node's parents.
      Returns:
      The score, or NaN if the score cannot be calculated.
