Talk:Negative predictive value

merge
request merge of "negative predictive value" "positive predictive value" and "Sensitivity and specificity". these terms are intimiately related, and should be in one place, possibly with a discussion of ROC. Further, suggest modeling on > this is a great expostion of this complicated stuff.Cinnamon colbert (talk) 22:24, 16 November 2008 (UTC) PS: the three articles are a great start


 * I completely agree, NPV and PPV should be brought together; I'll set about working on this soon Eps0n (talk) 23:57, 4 November 2009 (UTC)

Table and edits
See Talk:Sensitivity (tests) re past wish list for simpler description, setting what it is before launching in mathematical jargon. I have also added a table and in Sensitivity (tests) added a worked example. The table is now consistant in Sensitivity, Specificity, PPV & NPV with relevant row or column for calculation highlighted. David Ruben Talk 02:45, 11 October 2006 (UTC)

I changed the third sentence - as already described in the last sentence of the opening paragraph, a high negative predictive value says nothing about the likelihood of a test being correct in the event of a positive result, just a negative one. — Preceding unsigned comment added by 60.240.104.183 (talk) 12:23, 16 June 2013 (UTC)
