In the regression case, coverage is the percentage of target values in the test data that
fall within 95% prediction intervals computed for the test instances. This is only
available for classifiers that implement the IntervalEstimator interface.
The relative error (as opposed to the relative absolute error or the root relative squared
error) is not available in the Explorer. However, it is possible to plug in new evaluation
You can also output the predictions and actual values and compute the relative error that

What exactly does "Coverage" mean in the evaluation of classification models in
WEKA (especially in regression models)?
Which error measure can tell the deviation (in relative units) from the actual class
