Unclear contribution by Texyalen
The recent contribution by User:Texyalen doesn't seem very useful to me without some explanation or at least one or two sentences of context. On the other hand, it will be very confusing or even deterring to beginners. Also, I can't make any sense out of some of the terms (see also copyedits by later contributors). Note that (1) Texyalen has posted the exact same content on Log-rank test and Logistic regression (there even a second time), and (2) they have refused to discuss any of their contributions [1].
If you want to add this back into the article, please refine it and make it understandable - or, even better, put it in one of the introductory articles on the topic, or create one in its own right. Here is the full contribution of Texyalen (with copyedits by others and demoted heading):

Student t test
What are people's thoughts about changing this to the Student t test, with an italicized t? This removal of the possessive and use of italics is as per AMA style. Removing the hyphen is also according to AMA style, but it is also just logical; the hyphen should be retained only if the term is being used as a modifier (eg, "the t-test results"). Any objections?
- Well, no objections have been made. If some of you do object, maybe me being bold and making the aforementioned change will spur you to comment so we can discuss the issue properly.211.23.25.61 (talk) 07:12, 20 April 2016 (UTC)

Sample size formula
Is there a reason why sample size planning for Student's t-test is not discussed in this article?
