The green one was created using a Decision Tree tool. Because the underlying data is not linear, the decision tree was able to model it with a higher R^2 (=.8) than the linear regression (R^2 = 0.01). This is part of what makes statistics so much fun!

Nettet2. jun. 2014 · 0. Model Trees differ from Decision Trees because they compute linear approximation (instead of constant ones) fitting simple Linear Models in the leaves.
