Examples of weka.classifiers.evaluation.NumericPrediction.actual()

weka.classifiers.evaluation.NumericPrediction.actual()
Gets the actual class value. @return the actual class value, or MISSING_VALUE if noprediction was made.

      NumericPrediction pred = preds.get(i);
      String instNum = pad("" + (instanceNumberOffset + i + stepAhead), " ",
          maxColWidth, true);
      temp.append(instNum + "  ");


      double actual = pred.actual();

      if (Utils.isMissingValue(actual)) {
        actualS = pad("?", " ", maxColWidth, true);
      } else {
        actualS = Utils.doubleToString(actual, 4);
