Talk:Negative predictive value

From Wikipedia, the free encyclopedia

[edit] 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)
