WebHere, we split the input data ( X/y) into training data ( X_train; y_train) and testing data ( X_test; y_test) using a test_size=0.20, meaning that 20% of our data will be used for testing. In other words, we're creating a 80/20 split. Shuffling (i.e. randomly drawing) samples is applied as part of the fit. WebTo your other two points: Linear regression is in its basic form the same in statsmodels and in scikit-learn. However, the implementation differs which might produce different results in edge cases, and scikit learn has in general more support for larger models. For example, statsmodels currently uses sparse matrices in very few parts.
