WebYou can see from this diagram that the final selected tree has eight leaves. For a regression tree, the shade of the leaves represents the predicted response value, which is the average observed logSalary for the observations in that leaf.

For example, let y be a vector of response values for all observations landing on a specific node of the decision tree. The value predicted by the tree for this node is then mean(y).The MSE associated with this node is var(y,1).The weighted MSE used to compute the split gain is …
