    Returns an N*2 array, where N is the number of possible classes, that estimate the boundaries for the confidence interval with a confidence level specified by the second parameter.

      double[][] predictInterval(Instance inst, double confidenceLevel) throws Exception
      Returns an N*2 array, where N is the number of possible classes, that estimate the boundaries for the confidence interval with a confidence level specified by the second parameter. Every row of the returned array gives the probability estimates for a single class. In the case of numeric predictions, a single confidance interval will be returned.
      参数:
      inst - the instance to make the prediction for.
      confidenceLevel - the percentage of cases that the interval should cover.
      返回:
      an array of confidance intervals (one for each class)
      抛出:
      Exception - if the intervals can't be computed
