ROC also gives a numerical representation of the classifier performance when providing the “area under the curve” (AUC) value. An AUC of 0.5 corresponds to no classification power at all, and an AUC value of 1 denotes a perfect biomarker. In addition to a p-value and an AUC value...

在ROC curve analysis对话框中,Variable框中选择testb,Classification variable框中选择disease,其他默认即可,最后点击OK。 4、结果解读 下表给出了总样本量、disease=0组的频数(百分比)、disease=1组的频数(百分比) 下表给出了ROC分析的结果,ROC曲线下面积AUC=0.798,95%可信区间为0.735-0.851,z值=9.546,p值<0.000...
By the technique of ROC curve analysis, we find that the accuracy and efficiency of topology identification is mainly determined by coupling strengths. The success rate of estimation will be reduced if the coupling is too weak or too strong. The presence of noise facilitates topology ...
