Basic regression trees partition a data set into smaller groups and then fit a simple model (constant) for each subgroup. Unfortunately, a single tree model tends to be highly unstable and a poor predictor. However, by bootstrap aggregating ( bagging) regression trees, this technique can become quite powerful and effective. corporation stock certificate example
