This is because the method only splits tree nodes if the resultant decrease in the sum of squares error exceeds some threshold. This means that the method will only split tree nodes if it is confident that the split will improve the model&#8217;s performance. As a result, the method will tend to produce smaller trees than other methods.<\/p>\n<p>The described method also has the potential to affect the performance of the resultant regression\/classification model.
