中文摘要 | 在臨床醫學上,常以醫學檢測來判斷個體是否受到病毒或細菌感染。而在判斷過程中常有多種檢測法並行的情況。鑑於成本及病人施行各種檢測的意願低落,實有必要比較各種檢測法之正確率。本研究使用多維二項模式討論各檢驗正確率之比較,提出一檢定統計量,檢定各種檢測法在統計是否有顯著性差異,並計算定臨界值。在小樣本及高正確率之情況,我們提出的方法比McNemar檢定有更好的結果。在實證上,我們以受幽門螺旋桿菌(Helicobacter Pylori)感染的消化性潰瘍病人,分別施以數種檢驗幽門螺旋桿菌是否存在的方法所得的資料,檢定各種檢測法的在統計差異顯著性,並有不錯的檢定結果。 |
英文摘要 | In practice, we often apply several medical exams on the same person to diagnose whether the individual was infected or not. Considering the cost and the patient's willing of taking several medical exams, there is a need to compare the detective rates of the medical exams. In this study, we propose a testing statistics as well as the computation of the critical values to compare the positive rates between two medical exams. The testing method is better for the small sample data with high detective rate comparing to the McNemar Test. We also apply this procedure to a set of data, contained with the results of the medical exams of detecting the infection of the helicobacter pylori, to compare the detective rates of these medical exams. And we get a quite informative result. |
