@J-J-J No way to fix it that I know about. If the OP did not tell us his application, it would not have been closed!

@J-J-J I understand your reaon to close, but the close reason displayed is simply wrong. "Not about statistics"? It is, and can probably be answered. See for instance pnas.org/doi/abs/10.1073/pnas.97.22.11885

@User1865345 I'm probably lucky to (almost) never have been thought in cookbook-style. My first textbook in stats (after kai Lai Chungs prob book) was Larsen & Marx, The second was Bickel & Doksum

@User1865345 An answer to that posts points out that "red flags" (spamming, rude) has cross-site effect. So use those!

This question stats.stackexchange.com/questions/352046/… lacked the biostatistics tag, and so was maybe missed by experts in that area. It is intriguing, could somebody have a look?

There seems to be an alternative to the chisquared test, in place of $\sum (O-E)^2/E$, just do $\sum (O-E)^2$, this is asked about at stats.stackexchange.com/questions/605760/…. I once found a paper about this, but cannot find it again now. Anybody knows?

@shintuku There is a lot of information on this site, search the site for association, start with stats.stackexchange.com/questions/534454/… and links therein. Also look there in the right margin for the entries linked and related

There is still a problem with too many close-votes for perfectly on-topic Qs related with software. This Q stats.meta.stackexchange.com/questions/5985/… needs an official answer! An example today is stats.stackexchange.com/questions/581702/…

I thought I remembered a post here about "regression clustering" (?) : 2 groups with different regression lines, but group ids lost, so cluster and regress simultaneously ? What is this named? Good posts, or other references? Searching is difficult (trying to hint at stats.stackexchange.com/questions/539357/…)
