How to plot ROC curve and compute AUC by hand
Web1. Look at the ROC curve.The curves should be entirely above the diagonal line. If any curve falls below the line, then the test is not interpreted. 2. Look in the Area Under the Curve table, under the Aysmptotic Sig. column. These are the p-values that are interpreted. If a p-value is LESS THAN .05, then the test does a significant job at diagnosing disease states. Web12 dec. 2015 · I am planning to use repeated (10 times) stratified 10-fold cross validation on about 10,000 cases using machine learning algorithm. Each time the repetition will be done with different random seed. In this process I create 10 instances of probability estimates for each case. 1 instance of probability estimate for in each of the 10 … WebThe ROC curve plots the False Positive Rate (FPR) on the X-axis and the True Postive Rate (TPR) on the Y-axis for all possible thresholds (or cutoff values). True Positive Rate (TPR) or sensitivity: the proportion of actual positives that are correctly identified as such. michelle snyder ibclc npi
