Afortunately there is the following page in which they only use TP,FP, TN, FN that is true/false and positive/negative. So replace that page with https://en.wikipedia.org/wiki/Precision_and_recall or change notation. Please.
P = TP + FN is something that I would never put on paper.
Also, why are you creating a chat thread on Hacker News with a plea to delete a page on Wikipedia?
Also TP + FN = Prevalence of the desease, but using P for prevalence and for positive creates a lot of confusion in a wikipedia page to explain a concept.
My plea is that I don't want people to get confused. On top of it there is a warning on that page of wikipedia: This article may be too technical for most readers to understand. I couldn't understand why they used that notation. So I ask to delete that page because is going to confuse people.
1) Is P=TP+FN the standard notation in the area?
2) Is that notation confusing to people outside the area?
3) How is TP+FP called in that area?
Nobody's using P for prevalence. It's being used for positive. Take a look at the table.
> that is the number of d[i]seased people
Yes, that is what "positive" means. (In the context of a test for disease.)
