Plot Ridge coefficients as a function of the regularization
===========================================================

.. currentmodule:: sklearn.linear_model

Shows the effect of collinearity in the coefficients or the
:class:`Ridge`. At the end of the path, as alpha tends toward zero
and the solution tends towards the ordinary least squares, coefficients
exhibit big oscillations.
