- Method Detail
  - updateStatsForIntervalEstimator
```
void updateStatsForIntervalEstimator(IntervalEstimator classifier,
                                     Instance classMissing,
                                     double classValue)
                              throws java.lang.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:
    
    java.lang.Exception - if intervals could not be computed successfully
  - toSummaryString
```
java.lang.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
