WebPrediction Trees are used to predict a response or class \(Y\) from input \(X_1, X_2, \ldots, X_n\).If it is a continuous response it’s called a regression tree, if it is categorical, it’s called a classification tree. At each node of the tree, we check the value of one the input \(X_i\) and depending of the (binary) answer we continue to the left or to the right subbranch. WebCompare this pruned tree with the one obtained with the regression trees implementation in rpart. In particular, we can compare the predictions of this other pruned tree on the test set: pr.tree <- predict (bos.pr2, newdata = dat.te, type = "vector") with (dat.te, mean ((medv - pr.tree)^2)) Note that the predictions of the tree pruned with the ...
