... bagging is more extensive. The alternative forecasts may come not from different models per se, but from bootstrapping the initial training set. As we discuss in Section 4. 2.8, bootstrapping involves ... resampling the original training set with replace- ment, and then taking repeated forecasts. Bagging is particularly useful if the data set exhibits instability or structural change. Combi...
