The title basically tells it. Multilevel models are pretty popular as a question topic and it might be good to have a separate tag for the nonlinear type. But I'm not sure if it's needed.

    $\begingroup$ You see a case, and at worst tags that are not used much don't seem any kind of problem, so I say "Go for it!". $\endgroup$

    $\begingroup$ At a minimum, if you create one, be sure to make a good wiki excerpt for it to guide its usage. $\endgroup$ Jan 15 at 12:32
  • $\begingroup$ Peter, could you at least show how many questions on this topic have appeared over the past month or so? Albeit I am not acquainted well with the topic, I agree with you but would have a better insight if we get the numbers (not that it is directly related to the aptness of the tag, but still). $\endgroup$ Jan 15 at 12:34

    $\begingroup$ The fact that a tag might be rarely used shouldn't itself be a deterrent. In fact tags that are very often used can be problematic too, because there is so much stuff to look at, although scanning by votes can help. $\endgroup$

    $\begingroup$ If the new tag stays at 1 for half a year, it will be removed, so at least try to find a few other posts to retag $\endgroup$ Jan 15 at 13:00
  • $\begingroup$ Agreed with every word @NickCox. As I said, this should not be the core factor for assessing the creation of the tag. I only wanted to know the frequency which can be partly relevant. $\endgroup$ Jan 15 at 13:04
  • $\begingroup$ I added the tag and a brief Wiki. I'll try to find some more examples. $\endgroup$

    $\begingroup$ @PeterFlom, I have added the link to the tag, you created in the post. $\endgroup$ Jan 15 at 15:54

    $\begingroup$ The tag description says the dependent variable is not continuous, but the tag's name does not reflect that. What tag should be used for nonlinear multilevel analysis where the dependent variable is continuous? Perhaps it would be good to include guidance on this in the tag description? $\endgroup$ Jan 22 at 10:30
  • $\begingroup$ @RichardHardy Can you add that? Thanks! $\endgroup$

  • $\begingroup$ @PeterFlom, I could add that, but first I need an answer to my question. Otherwise I do not know what to add. $\endgroup$ Jan 22 at 12:10
  • $\begingroup$ @RichardHardy I am not sure of the answer. Maybe we need to revise the "not continuous"? What case of nonlinear MLM with a continuous DV are you thinking of? $\endgroup$

  • $\begingroup$ I don't know. I was just guessing that they exist. What type of models with discrete dependent variable do you have in mind under the new tag (if discrete is what you mean by not continuous)? $\endgroup$ Jan 22 at 12:36
  • $\begingroup$ Logistic (either regular, or multinomial, or ordinal) or a count model. Maybe others as well. $\endgroup$
