All Implemented Interfaces:

RevisionHandler
```
public class PairedStatsCorrected
extends PairedStats
```
A class for storing stats on a paired comparison. This version is based on the corrected resampled t-test statistic, which uses the ratio of the number of test examples/the number of training examples.
