Method Summary

Modifier and Type	Method and Description
String	toSummaryString() Return a formatted string (suitable for displaying in console or GUI output) containing all the statistics that this metric computes.
void	updateStatsForIntervalEstimator(IntervalEstimator classifier, Instance classMissing, double classValue) Updates stats for interval estimator based on current test instance.

Method Detail

updateStatsForIntervalEstimator

void updateStatsForIntervalEstimator(IntervalEstimator classifier,
                                     Instance classMissing,
                                     double classValue)
                              throws Exception

Updates stats for interval estimator based on current test instance. Implementers need only implement this method if it is not possible to compute their statistics from what is stored in the base Evaluation object.

Parameters:

classifier - the interval estimator

classMissing - the instance for which the intervals are computed, without a class value

classValue - the class value of this instance

Throws:

Exception - if intervals could not be computed successfully

toSummaryString

String toSummaryString()

Return a formatted string (suitable for displaying in console or GUI output) containing all the statistics that this metric computes.

Returns:

a formatted string containing all the computed statistics
