聽聽統計學家怎麼看藥檢這件事 http://www.npr.org/templates/story/story.php?storyId=93424870 Cyclist Floyd Landis was stripped of his 2006 Tour de France title after he tested positive for synthetic testosterone. Donald Berry, a statistician at the University of Texas, doesn't buy it. Berry explains how drug testing could be more scientific. Don Berry is the chairmain of department of Biostatistics at M. D. Anderson Cancer Center. He is famous for his work in Bayesian statistics. 有興趣的人可以去看看Don最近發表在nature上的commentary The science of doping http://www.nature.com/nature/journal/v454/n7205/full/454692a.html keys of the discussion: * It is too quick to assume that a positive test means a guilty athlet; * The processes used to charge athletes with cheating are often based on flawed statistics and flawed logic; * The problem with multiples: false positive rate is magnified by the number of tests. ※ 編輯: bmka 來自: 137.187.153.83 (08/13 01:17)
