I want to generate a ROC curve for the data in the attached excel sheet. I am using the following code: meanthresh = 0.8:0.1:2.5; % This alters the mean threshold between 0.8 and 2.5 by 0.1 %% Beginning the Mean ROC for a = 1:length(meanthresh) %% the for loop makes it to ...
Receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of resting heart rate for mortality in patients with AF&CHD. The analysis yielded an AUC 95% CI: 60.383% (57.0596% ~ 63.7064%), as shown in Supplementary Material 1. Fig. 1 Kaplan–Meier ...
