- - ### Method Detail

    - #### predictIntervals

          double[][] predictIntervals(Instance inst,
                                    double confidenceLevel)
                                      throws java.lang.Exception

      Returns an N * 2 array, where N is the number of prediction intervals. In each row, the first element contains the lower boundary of the corresponding prediction interval and the second element the upper boundary.
      Parameters:
        `inst` - the instance to make the prediction for.
        `confidenceLevel` - the percentage of cases that the interval should cover.
      Returns:
        an array of prediction intervals
      Throws:
        `java.lang.Exception` - if the intervals can't be computed
