Do we really need two tags for
[nonparametric]? I propose that we have a single tag that covers both.
Given that existing usage has favored Updated suggestion: We create a new tag and map both of the original tags to it. To wit:
np, we could make that the master, but also update the excerpt / usage guidance and full wiki.
[nonparametric]1,290 threads, an excerpt & wiki
[parametric]252 threads (of which 95 have both), an excerpt, but no wiki
The current excerpts are,
Procedures that rely on relatively few assumptions about underlying probability distributions.
Statistical models described by a finite number of real-valued parameters. Often used in contrast to non-parametric statistics.
I'm certainly open to discussion about the new excerpt / usage guidance, but the kind of thing I have in mind might be:
Use this tag to ask about the nature of nonparametric or parametric methods, or the difference between the two. Nonparametric methods generally rely on few assumptions about the underlying distributions, whereas parametric methods make assumptions that allow data to be described by a small number of parameters.
Note that this excerpt has 312 characters, which is longer than the typical excerpt, but well within the limits, and would not be the longest excerpt, even among the top tags.
mean and average---do we really need both? For me those are synonyms, both have wikis, the one for means mentions expected value, otherwise both mentions location estimators. Since there is a separate tag for expected value, that part could be removed from wiki for mean. From browsing some posts I can see no clear difference in usage.
