I suggest merging arch and garch tags, or making arch a synonym of garch (I am not sure how I should formulate this correctly).
- I don't see sufficient conceptual difference between ARCH and GARCH models to maintain both tags.
- GARCH is more general, so I suggest keeping garch as the tag name to remain.
- arch has 41 questions while garch has 292; only 11 questions are tagged with arch without garch.
- I have checked the questions tagged arch without garch and I do not see that they would be sufficiently special to deserve a separate tag.
If the community agrees (we will see), how can this be done? It would be nice to get rid of arch in a way that it would not reappear soon thereafter and there would not be a need to raise the question again.
Edit: vote here in the thread for suggested synonyms.
arch
intogarch
is essentially the same kind of proposal as one suggesting mergingautoregressive
intoarma
(both of which currently exist, by the way, as domoving average

) $\endgroup$
