Linear Regression vs. Regression Tree

Loading the Auto-MPG data from a table.Splitting the data into the training and testing data sets Regression modelsRT Parameters are:-Tree depth = 3-Minimum node size = 10 Regression models on Auto+MPG data setThis workflow shows a regression tree to model MPG (milesper gallon) of cars based on their HP (horsepower). Thisexample uses the Auto MPG Data Set from the UCI MachineLearning Repository (https://archive.ics.uci.edu/ml/datasets/Auto+MPG).
