Method Detail

predictIntervals

double[][] predictIntervals(Instance inst,
                            double confidenceLevel)
                            throws 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:

Exception - if the intervals can't be computed
