[WIP] Add Dataframe to Inference Data Example to cookbook

[Rishabh261998]

Description

closes #1490

This is an update on the issue "Add dataframe to InfData examples to cookbook" #1490 I have added the example but there seems to be a problem i.e the created inference object does not have any attributes(eg: created_at, arviz_version). Could you help me tackle this and also provide your feedback. Thanks

Hi, @OriolAbril can you check the PR and provide anything which I need to update and also the problem which I suggested in the description. Thanks

I would use az.InferenceData(posterior=xdata) like it is done in the snippet in the issue instead of convert_to_inference_data. As we already have Dataset objects, using InferenceData will be more flexible and would allow for example creating multiple groups at once, which convert... does not.

Regarding the attributes, do not worry about it. Attributes are added when converting to xr.Dataset which all the other examples in the notebook do under the hood. Here however, the Dataset is created manually, so attributes will not be present unless they are manually added.

Thank You for your feedback @OriolAbril, I will change the convert_to_inference_data to InferenceData(posterior=xdata). I was also wondering about the 3 unsuccessful checks, is it ok for me to ignore them for now?

[OriolAbril]

Yes, you can ignore them for now

@OriolAbril is there anything more which I need to update? Thanks

Can you rebase with the latest changes from main and then add a bullet point about the change in the changelog?

@OriolAbril I was just going through the CHANGELOG.md file and just found out a typo. The first bullet point in the unreleased version links to the PR 1535 but should link to 1518. Thanks

[OriolAbril]

Thanks, we can fix this in #1550
