WebStep 1/3. test-set accuracy of logistic regression compares to that of decision trees. However, here are some general observations: Logistic regression is a linear model that tries to fit a decision boundary to the data that separates the two classes. Decision trees, on the other hand, can model complex nonlinear decision boundaries. WebA regression tree is built through a process known as binary recursive partitioning, which is an iterative process that splits the data into partitions or branches, and then continues …
