.. _example_linear_model_plot_ridge_path.py: =========================================================== Plot Ridge coefficients as a function of the regularization =========================================================== Shows the effect of collinearity in the coefficients of an estimator. .. currentmodule:: sklearn.linear_model :class:`Ridge` Regression is the estimator used in this example. Each color represents a different feature of the coefficient vector, and this is displayed as a function of the regularization parameter. At the end of the path, as alpha tends toward zero and the solution tends towards the ordinary least squares, coefficients exhibit big oscillations. .. image:: images/\plot_ridge_path_001.png :align: center **Python source code:** :download:`plot_ridge_path.py ` .. literalinclude:: plot_ridge_path.py :lines: 19- **Total running time of the example:** 0.52 seconds ( 0 minutes 0.52 seconds)
