Thanks for rewriting the doc string. I have two things that could be added:

• N is the length of the simulated signal in samples, right? I think this is at the moment only implicitly mentioned.
• Maybe you could write "autoregressive (AR)" instead of only "AR" because there might be users who don't know what the abbreviation stands for.

I would suggest merging your changes in the joss-doc-suggestions branch so that all changes related to the JOSS docs review are in the same place. But I don't know whether it's easily possible to change this in the existing PR. But since it's only a small change it might not matter too much.

done :)
