Regarding filling the tag excerpt:
What can be done when the tag name represents both a function of a statistical software, but its name also suggests a broader concept of usage?
The lme tag, which is a function in R, but it is also an acronym (in a broader sense) for linear mixed effect model. CV has other tags for mixed effect models, but none for linear mixed effect models (besides lme).
I had read once on an SO meta post that it was not a good idea to create a tag to refer only to software functions. Unfortunately, I did not find this post. I found this one, which does not have a +10 upvoted and accepted answer.
So, after research, I count 42 posts out of 64 (63.7%) tagged if lme were also labeled with r.
I thought of suggesting an excerpt which could convey the broad sense, but also emphasizing the R aspect of its usage.
From FOX, J. (2002) Linear Mixed Models. Retrieved from here (page 1, last paragraph), I came up with this suggestion for the tag excerpt:
Linear mixed models may be expressed in different but equivalent forms. In the social and behavioral sciences, it is common to express such models in hierarchical form. "lme" also stands as an R function in the formulation described in Laird and Ware (1982) but allowing for nested random effects.
The suggestion was rejected but with different opinions from the reviewers.
So, the objective here is to ask if we have a consensus of what to do when there is a tag that is strongly related to a specific software, but it can also be used for broader concepts, or even in different software. How to fill in the tag excerpt in such situations? And beyond that, are software function tags recommended or not?
