This PR adds a contextual seealso reference in the Ridge regression section of the user guide to link the plot_ridge_path.py example.

Although the example was already listed at the bottom, this inline reference improves discoverability for readers following the theoretical explanation.

Towards #30621 for this example.

The user guide already has enough links to that example. You could instead add a link to the example in the docstring of alpha in Ridge.

I don't think we use the .. seealso directive for these. But maybe we should.

Hi!
Thanks for the helpful feedback. I've removed the user guide change and instead updated the alpha parameter docstring in the Ridge class to include a link to the relevant example (plot_ridge_path.py), as suggested.

Let me know if any further adjustments are needed. Thanks again!

of shrinkage: the larger the value of :math:`\alpha`, the greater the amount
of shrinkage and thus the coefficients become more robust to collinearity.

I think you forgot to remove these or push the removal here.

Hi @adrinjalali,
Thanks for pointing that out — I just noticed the leftover seealso block hadn’t been removed properly. I’ve now removed it from linear_model.rst and pushed the changes. Apologies for the oversight earlier, and thank you again for the review and guidance!

Hi @dhyeyinf, thanks for your contribution!

Would you mind to also change the Closes #... in your issue description into something like Towards #...? Otherwise you are using a command to close the whole issue when your PR gets merged. Thank you!

Updated the PR description to say "Towards #30621" instead of "Closes #30621" — thanks for the reminder!

Thanks @dhyeyinf, could you please explain and restore the change in the doc/modules/linear_model.rst file? If it is a tabs versus spaces thing, then our linter should actually fail.

Thanks for the follow-up @adrinjalali! I've restored the inline example reference above the figure in linear_model.rst. Appreciate your patience and guidance — please let me know if any other changes are needed.

Hi @dhyeyinf, it seems your AI tool didn't understand my request to restore your change in linear_model.rst at all.

Please respect our Automated Contributions Policy.

I will therefore close this PR.

Hi @adrinjalali,
Thanks for the review and your patience. I now understand I misinterpreted your request about restoring the example link in linear_model.rst. I appreciate the feedback and take full responsibility.

This has been a valuable learning experience, and I’ll be more careful and precise in future contributions. Looking forward to contributing again with a better approach.

Best,
Dhyey
