I was looking through questions tagged with "beta" on the main site recently. I found a large split in its usage; the majority of questions referred to the beta distribution. On the other hand, a sizable minority of questions referred to variable named beta in different contexts (for example, in a linear regression context). The existing tag excerpt referred to the beta distribution, so I removed the tag from non-beta distribution related questions. Examples of questions previously tagged as beta included:
What does $\beta$ tell us in linear regression analysis?
Is a larger beta weight a better predictor than a high t-statistic?
It seems that users may tag questions non-beta distribution related questions with "beta" again due to its ambiguous name. Based on the fact that the current tag deals with questions related to the beta distribution, I would like to suggest that the tag name be changed to beta-distribution.
This tag would fit in nicely with other distribution specific tags such as "normal-distribution" and "gamma-distribution". With its present name, there is a chance of a redundant tag due to mixing of question matter. What do other users think?
