I find the code above quite complex. You can replace it with our available helper function from scikit-learn:
from sklearn.datasets import make_regression
from sklearn.model_selection import train_test_split
n_samples_train, n_samples_test, n_features = 75, 150, 500
X, y, coef = make_regression(
n_samples=n_samples_train + n_samples_test,
n_features=n_features,
n_informative=50,
shuffle=False,
noise=1.0,
coef=True,
)
X_train, X_test, y_train, y_test = train_test_split(
X, y, train_size=n_samples_train, test_size=n_samples_test, shuffle=False
)

Hi @glemaitre, I updated the code for generating data. Let me know if I should change anything else! |

Thanks @brendo-k LGTM. It is always nice to see an improvement in the documentation changing some code from 11 years ago by new helpers that have been proposed on the development path. |
