We have a tag with 20 Qs, no wiki excerpt, and a synonym .

Wikipedia mentions at least three different interpretations of the term: https://en.wikipedia.org/wiki/Data_generating_process

It seems to have a specific meaning in econometrics, from which the acronym DGP appears to be derived, see for example here or here, or even more generally in the context of regression, where the population regression function PRF is a feature of the DGP.

However, vaguer usage of the term, similar to the first definition give in Wikipedia ("the data-collection process") also seems to be used elsewhere, e.g. here.

In what sense is it supposed to be used on CrossValidated? I.e., what should be its usage guidelines?

    $\begingroup$ I don't think that Wikipedia page is very good. OTOH, I'm not sure if we really need a [dgp] tag, either. I'll have to look at some & see how the tag helps categorize the information. $\endgroup$

    $\begingroup$ Seeing that there are only 20 Qs in this tag, I also doubt we really need it. $\endgroup$

  • $\begingroup$ @amoeba Wait, should both [dgp] and [data-generation-process] be eliminated? Or just the latter? EDIT: never mind, I forgot that dgp is a synonym of data-generation-process $\endgroup$

I looked into it and it seems that is a pretty useless tag that should be eliminated. In most cases people seem to be using it instead of our well-established tag, which only creates confusion.

With only 20 Qs, eliminating this tag is an easy task that can be done in around 3 sittings (see When re-tagging old threads, how many should one do at once?). You now have 2k rep and so are able to edit questions; if nobody protests here in a day or two, it would be great if you could do it.

Update: Done by @Chill2Macht, thanks!

    $\begingroup$ By the way, @Chill2Macht, if you are interested in doing some tag work, I can point you to some ongoing or queued retagging projects. Just let me know :) There is much more work needed here than there are people willing to help. $\endgroup$

  • $\begingroup$ That sounds interesting to me -- I don't know in advance if I would have time for all of them, but certainly it would be worth looking into $\endgroup$

    $\begingroup$ @Chill2Macht You can basically navigate our Meta and look for topics in tag-reorganization. Here is the latest issue that I posted yesterday: stats.meta.stackexchange.com/questions/4774 -- this one is an easy job. There are other pending issues that require substantial work: e.g. stats.meta.stackexchange.com/questions/4306, or stats.meta.stackexchange.com/questions/3065, or stats.meta.stackexchange.com/questions/4248. There are also tags to be removed: stats.meta.stackexchange.com/questions/3031 where some tags can be done manually. $\endgroup$
