Add accuracy?

Could somebody add Accuracy the bottom right as in this table?

What does this show?
I don't understand what this diagram shows. What do the different colors stand for? Why are the things in the two right columns grouped together? I understand each of the terms, but I don't think the diagram helps to organize the concepts, at least not as currently designed. Sancho 21:08, 30 March 2016 (UTC)
 * Their relationships are rather complicated and the formulas are given in the table. The colours attempt to show combinations: e.g. if Z = Y / X, Z's colour is roughly a mixture of Y's and X's. Additionally, true positive and true negative are biased towards green, and false positive and false negative are biased towards red.


 * I've added this map of relationships, but if it's still confusing, I'd appreciate suggestions to improve it. Thanks, cm&#610;&#671;ee&#9094;&#964;a&#671;&#954; 23:56, 28 June 2017 (UTC)


 * This chart is incredible. It's been incredibly useful to me as I sort through the different measures of accuracy. Would you be open to a couple of ideas to make it more approachable? (right now it's propping up a bunch of highly technical and esoteric pages in which it is the only shining light).
 * Also, I'm new to Wikipedia, so this may not be the right way or place to communicate. I'm open to moving Cnrmck (talk) 03:35, 15 March 2018 (UTC)


 * Thanks for your thoughts. Yes, I'd certainly like to hear your ideas on improving it. I know it's grown messy and much appreciate suggestions to make it clearer while retaining the information.
 * This is also a good place to keep the conversation going. May I just request for


 * to be added to each message to me, as you've done; otherwise I may miss your messages? Thanks, cm&#610;&#671;ee&#9094;&#964;a&#671;&#954; 02:09, 18 March 2018 (UTC)

Power?
Hi, I don't see why "Power" appears in the top-left cell of the 2x2 table. In this context, power should correspond to something like (# true positive) / (# condition positive), i.e., "TPR" or "sensitivity" or "recall". It definitely isn't just the number of true positives. In any case, the "power" terminology is common in the context of a formal statistical hypothesis test but rarely used in diagnostic settings (where TPR/sensitivity/recall are used instead).

This table is (a) already jam-packed and (b) an incredibly useful resource, so I hope there is consensus around the small improvement of deleting the word "Power".
