Please post your tag synonym suggestions as new answers in this thread, one answer per suggestion. Upvote answers where you believe that the suggested tags should be made synonyms, and downvote answers where you believe the tags should remain separate. Well upvoted suggestions will be eventually implemented by the moderators (and then the corresponding answers will be deleted).

GPT is just one well-known example of a Large Language Model (LLM), but has no wiki and only 6 questions. LLM is more general, and has a wiki.

(1381) $\leftarrow$ (574)

EDIT:

usage guidance (there is no wiki entry):

Data, events, processes, etc, are non-independent if knowledge of 1 provides some information about the state or value of the other.

usage guidance (more info at wiki entry):

Events (or random variables) are independent when information on some of them tells you nothing about the probability of occurrence (/ distribution) of the others. Please DO NOT use this tag for independent variable use [predictor] instead.

These are literal opposites and I don't see any need for them both to exist.

Not sure, but perhaps:

(5495) $\leftarrow$ (1450)

I suppose one can have a model with only random effects and no fixed effects, which would make it different from a mixed model, though I don't think the conceptual distinction is so large that it would merit a separate tag. And I think all the questions I've seen with this tag are about using random effects in mixed models.

    $\begingroup$ The decision is problematic at the very first place. It is not a formal term and is prone to be used in a random way by a random user. If the decision-theory is more apt at any place, only it should be used there. Let the decision tag be exiled in favor of the more appropriate [decision-theory]. If the former is used somewhere as the latter's synonym, then those posts ought to be re-tagged, imo. $\endgroup$

(266) $\leftarrow$ (6)

EDIT: has no usage guidance or wiki. has usage guidance:

Pooling, eg for variance, is used when several groups or populations are assumed to have a common property (a common parameter value) and the information from all the groups or populations are used together to estimate that common property.

I think this usage guidance is broad enough to cover as well.

There seems to be a fair bit of overlap between:

(2573) and (5,774)

And the usage of (9591) overlaps a fair bit as well, though in principle it does differ more.

Is there a case for merging the first two? And perhaps editing the tag info for the third to make a distinction?

  • $\begingroup$ I'm not sure here ... why is p-values more related to statistical significance than to hypothesis testing? By the way, p-values have their own existence, now, without regard to where they come from ... and some uses of p-values can be seen as descriptive. $\endgroup$

    $\begingroup$ @kjetilbhalvorsen To your first point, Bayesian hypothesis testing exists although I doubt it appears often in questions with that tag. And as for the second, I'd be curious to see if that is a common view. I would have thought statistical significance and p-values would be hard to divorce from each other. To me, they seem much closer to each other than to hypothesis testing (which could itself be made a synonym quite reasonably, I think). $\endgroup$

There are now two tags, and essentially covering the same topic. I propose we let be the main one (even if is is newer and less used), as it is the most general one.

    $\begingroup$ (+1) I recently created pre-post-comparison because, as you note, there are several closely related topics (with quite a few threads) that are not covered by the much more specific change-scores. $\endgroup$

    Aug 21, 2022 at 17:51
  • $\begingroup$ I've come across questions under the mixed-model tag that might be appropriately tagged with pre-post-comparison too. But the terms "pre-post" (and variants) don't appear in the body of the question because the OP didn't think about it: 1. And here is a simply regression example: 2. It maybe challenging to apply the pre-post-comparison consistently? Or perhaps I misunderstand its application? $\endgroup$

    $\begingroup$ @dipetkov I frequently add relevant tags that the OP missed or is unaware of (often because they're unaware of the terminology). I also leave a comment suggesting that they look at the top questions in the tag if it's a question that is likely to have been addressed previously. $\endgroup$

    $\begingroup$ Scaling seems more generic. Maybe [n] & [st] should be grouped under [fs], & we could even create a [centering] tag to be a synonym as well? Dunno what's best here... We probably don't need 3 tags for this, though. $\endgroup$
    – gung - Reinstate Monica
    Feb 24, 2022 at 14:00
  • $\begingroup$ @gung-ReinstateMonica Is centering the same thing as scaling? I always thought scaling was a specific application of the multiplication function, but centering is a specific application of the addition function. (Leaving aside that multiplication itself is repeated addition. :) Do you have a new insight for me, gung? $\endgroup$

    $\begingroup$ here is my standard answer on the specific use of these terms, @Alexis, but I'm guessing fs is a generic term. I think these should be grouped together somehow, but how best to do it is unclear to me. The best superset name would probably be linear-transformation, but that doesn't seem like it would be a good choice for our situation. $\endgroup$
