WebbThere are several libraries we are going to import and use while running a regression model up in python and fitting the regression line to the points. We will import pandas, numpy, metrics from sklearn, LinearRegression from linear_model which is part of sklearn, and r2_score from metrics which is again a part of sklearn. WebbIn scikit-learn this can be done through the train_test_split () function, which returns the training and test data. Then, the model is fitted through the training data and its performance is tested through the test data. However, the described strategy does not permit to verify whether the model is overfitted or not. red desert 5 seconds of summerWebbAn extra-trees regressor.
