Requested move 8 June 2021

[edit]

Q-value (statistics)Q-value (statistics) – This page refers to the q-value popularised by JD Storey, which is related to false discovery rate and is calculated row-by-row in the table of results, giving an estimate of the proportion of false discoveries up to the current row; it's distinct from upper-case Q, which was used by Benjamini and Hochberg as the proportion of false discoveries in the entire experiment. Since Benjamini and Hochberg's nomenclature has become standard, and their contingency table with Q is widely used, I think it's misleading to use upper-case Q for this article, which describes something that Storey and others have always notated with lower-case q. I'm guessing that the upper-case Q here might have happened because it is the first letter of the title, but here, whether it is upper or lower case has real statistical meaning. I'm using the request-a-move template because (a) I'm inexperienced with wikipedia; (b) I'm not a statistician (there may be good mathematical reason for the upper case), and (c) I'm not totally sure what to do if, for stylistic reasons, it is vital that the first letter of a title must be upper case; can anyone think of a way to reorder the title so 'q' can be maintained?

I see I've failed totally. The whole point of the move is that 'Q' is utterly, totally, and completely, and frustratingly wrong. Upper case is not used by any of the authors who use this value. They use lower case specifically to distinguish it from upper-case Q which is something else altogether, though closely related. What on earth do we do about this? call it 'statistical q-value', 'FDR q-value', or 'Storey's q-value'? The last one won't work because it'll get jumped on by those who point out that Benjamini and Hochberg had similar ideas before Storey popularised them.

@Elemimele: Such move is not possible for technical reasons that are explained in WP:NCLOWERCASEFIRST. Instead, I've changed presentation of the title using the method in WP:DISPLAYTITLE and subsequently removed your RM request. No such user (talk) 12:14, 8 June 2021 (UTC)[reply]
@No such user: Thanks enormously, that's exactly what was required Elemimele (talk) 11:42, 10 June 2021 (UTC)[reply]
