標題: Re: [統計] 何謂Cohen's kappa(可汗的可怕?)
時間: Tue Dec 9 00:04:58 2008
kappa通常是用來評估一種分類或是一種指標的Inter-rater reliability
P - Pe
kappa = ----------------
1 - Pe
其中 P 是取樣樣本中,二次都被分在同一類的比率
Pe是若二次純粹照著一定的比例亂分,預期會分在同一類的比率
例如:
找A、B兩個病理科醫師看同樣100片檢體
其中有20片兩人都診斷為惡性腫瘤
10片A認為是惡性,B認為是良性
5片A認為是良性,B認為是惡性
剩下65片兩人都認為是惡性
那麼兩人診斷的一致率是 85%
然而A在100片中診斷30片是惡性,70片是良性
B在100片中診斷25片是惡性,75片是良性
如果A和B的診斷毫無關聯的話
(也就是當作A從100片中隨便抽出30片當作是惡性,而B也隨便抽25片當作是惡性)
那麼在B診斷為惡性的25片中,A恰好也診斷為惡性的期望值是 25*0.7=17.5 片
在B診斷為良性的75片中,A恰好也診斷為良性的期望值是 75*0.3=22.5 片
因此這樣隨便亂猜出來的一致率的期望值為 22.5+17.5 = 40%
0.85 - 0.4
得到 kappa = ---------------- = 0.75
1 - 0.4
因此可以說病理學上對惡性腫瘤的這套判斷準則
具有不錯的inter-rater reliability
若kappa小於0 , 表示取樣得到的一致率比隨便亂猜應得的一致率還低
一般當然認為兩者的測量結果無一致性
而分母除以 1-Pe , 是為了使得kappa的最大值為 1 ,這樣不同測量結果的
kappa值才能互相比較
kappa值愈接近1,代表這個分類方法的inter-rater reliability愈好
※ 引述《Holocaust123 (Terry)》之銘言:
: 正在看paper
: 在performance evaluation的地方作者用Kappa當作指標
: 上網查了Kappa的很多文章後 卻還是不知道卡巴的"統計意義"
: 有哪位好心的板友可以講解給我聽 或是丟個講義/網址都好
: 感謝..
