ROC curve analysis Description Allows to createROC curveand a complete sensitivity/specificity report. The ROC curve is a fundamental tool for diagnostic test evaluation. In a ROC curve the true positive rate (Sensitivity) is plotted in function of the false positive rate (100-Specificity) for di...
SPSS里面的ROC分析[ROC Analysis]过程可以实现比ROC曲线[ROC Curve]过程更多的功能,除了可以实现[ROC Curve]过程的各种功能外,还可以进行曲线的比较,绘制Precision-Recall曲线等。 Analyze>>Classify>>ROC Analysis… 将要检验的变量wfns、s100b、4变量模型预测值和2变量模型预测值放入检验变量框,状态变量选入结局变量ou...
下面的代码参考了《An Introduction to ROC Analysis》[2]中的算法 1(伪代码)。值得一提的是,知名机器学习库 scikit-learn 的 roc_curve 函数[3]也参考了这个算法。 下面我自己实现的 roc 函数可以理解为是简化版的roc_curve,这里的代码逻辑更加简洁易懂,算法的时间复杂度 O ( n log n ) O(n\log...

The classical (standard) approach of ROC curve analysis considers event (disease) status and marker value for an individual as fixed over time, however in practice, both the disease status and marker value change over time 但是遇到生存数据,比如随访的病人这个时间点没死,随访时间延长可能就死了,这个...
