what is the absolute score range in a roc curve why does each classifier produce both values of p value what score is used in calculating auc? can a classifier be positive how to calculate area of under curve what are the auc in a graph which score ranges should i use in the auc value do p value and acv in a roc curve work together? why is the auc value negative? how do i measure ap value for a roc curve plot? when using a roc curve what is the mean AUC score acc curves ap why does one classifier always produce positive scores how to calculate auc in roc curve how to determine ac in roc curve what is the auc value of two classifiers how to plot a roc curve when calculating auc how to calculate area of under curve roc curve when plotting a roc curve what score does the other classifier use
