Other than a few more suggestions, I am approving this patch. Thanks again, Marija!

However, I did not do a thorough review of the notebook content, shape, and prose. Let's also have @ckurze a final voice on it if he wants to. Thanks!

[ckurze]

Thank you for extending the notebook! Very good work. I added a few notes about typos.

[ckurze]

Fixed dependency to SQLAlchemy/Crate, and removed " at the end of requirements file.

Can someone merge this PR? For me, the merge is blocked.

[amotl]

For me, the merge is blocked.

The reason is this:

@ckurze needs to acknowledge this PR, because he requested changes on it. For this to optimally happen, you would have needed to re-request a review from him. I've just invoked the corresponding action for you.

Can someone merge this PR?

Sure. Thanks! Can I ask you to squash your commits beforehand?

[marijaselakovic]

I added a time series decomposition notebook as part of this pull request. Let's have that reviewed as well @ckurze @amotl

[amotl]

I don't think it is a good idea to add yet another piece to this PR, now that we have concluded the review process on the previous one. Please commandeer it into a different PR. Thanks!

[marijaselakovic]

Is the review process really completed? Merging was still blocked. The new piece is just a continuation of the previous one but put in a separate notebook for organizational reasons (easier for subsequent video creation.)

[amotl]

I think after resolving @ckurze's comments, it was just a technicality to acknowledge the review. Maybe he is not available now, so I also could have merged the PR after squashing the commit. I can't do the merge now after you added more content, apologies.

[ckurze]

Minor changes needed in Readme.md and the timeseries decomposition notebook.

[ckurze]

Time Series decomposition should be added to the readme file as well, incl. link to Colab.

[marijaselakovic]

The last commit updates README file.

[ckurze]

LGTM, thank you!

[ckurze]

@marijaselakovic Just restored the branch, can we harmonize the file names, please?

I'd prefer if (similar to the folder name), timeseries is just one word, pls. see screenshot.

Thank you!

Hi, thanks for your contribution, and congratulations for merging.

It is fine when a PR includes multiple commits which have a semantic meaning, but not like this:

In a situation like this, you usually squash the commits into one or multiple groups of commits before integrating them into the main branch.

I've just amended the history and force-pushed to main, in order to fix that. In that spirit, I am asking you to wipe your main branches, and pull again from remote.

Please branch off from a freshly fetched main, and submit a separate PR.
