I just looked at the wiki for
regression and it only discusses linear regression (OLS). Should it include a list of, links to, or even text about other forms?
This is what the current regression tag wiki excerpt says:
Techniques for analyzing the relationship between one (or more) "dependent" variables and "independent" variables.
I would be fine with amending this to something like:
Refers to techniques for analyzing the relationship between one (or more) independent and dependent variables using ordinary least squares (OLS). "Regression" is sometimes used loosely to include other types of models (logistic regression, Poisson reg., etc). For these, please consider: generalized-linear-model, logistic, probit, nonlinear-regression, etc, instead.
For the full wiki, I'm less concerned, as I think they are rarely read. (As a case in point, I gather you have only just read it, even though you've been a member for >2 years, and with >10k rep*.) Of course, that doesn't mean we should feel free to have just anything there, but I see no reason why some additional paragraphs couldn't be added (after what currently exists) stating that people sometimes include things like logistic regression under the the rubric of regression and linking to Wikipedia or other tag wikis. For what it's worth, I also tend to think of logistic regression as falling under some general heading of 'regression', which is ironic, since OLS regression is a special case of the GLiM instead. That is probably a misconception worth clarifying in the full wiki.
*This is in no way a criticism.
