  •   近幾年來,對於ROC曲線指標,有愈來愈多的文獻開始對於相似性及非劣性檢定方法提出相關的研究。例如:在醫學上一種新的非侵入性診斷方法與一種已被認定為標準的侵入性診斷方法做比較,也許在診斷的效率上並不一定相等,當經過相似性及非劣性的檢定,得到新方法與標準的診斷方法是相似的,若新方法在成本、使用方便性及安全性的考量下較優於標準方法時,將以新方法取代標準的方法。而本篇論文主要是利用無母數法、標準化差評估法、Kolmogorov-Smirnov法及拔靴法等四種方法評估相似性及非劣性的檢定方法,並以模擬結果比較這四種方法在常態分配假設、指數分配假設下的優劣。

     In recent years, for ROC curve index, more and more issues have focused on the equivalence or non-inferiority test. For example, in comparing diagnostic efficacy of a non-invasive alternative diagnostic procedure to an invasive method. If the non-invasive alternative procedure is equivalent to the invasive method, we may use the non-invasive alternative diagnostic procedure because of its easy administration, its better safety profile or its reduced cost. In this paper, the equivalence/non-inferiority tests based on four methods, the non-parametric method, method based on the standardized difference, method based on the Kolmogorov-Smirnov statistic, and bootstrap method are compared. A simulation study was conducted to empirically investigate the size and power of four methods for various combinations of distributions.
