What is AUC area under the curve?

The Area Under the Curve (AUC) is the measure of the ability of a classifier to distinguish between classes and is used as a summary of the ROC curve. The higher the AUC, the better the performance of the model at distinguishing between the positive and negative classes.

What is AUC in Wikipedia?

In the field of pharmacokinetics, the area under the curve (AUC) is the definite integral of a curve that describes the variation of a drug concentration in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry).

What does AUC mean in pharmacokinetics?

area under the curve
INTRODUCTION. In pharmacology, the area under the plot of plasma concentration of a drug versus time after dosage (called “area under the curve” or AUC) gives insight into the extent of exposure to a drug and its clearance rate from the body.

What is the area under ROC curve?

The Area Under the ROC curve (AUC) is a measure of how well a parameter can distinguish between two diagnostic groups (diseased/normal). MedCalc creates a complete sensitivity/specificity report. The ROC curve is a fundamental tool for diagnostic test evaluation.

How big is AUC?

Designed to accommodate 5,500 full-time students and 1,500 faculty and staff, AUC’s $400 million, 260-acre campus is technologically advanced and environmentally sensitive.

What factors are used to calculate AUC?

The area under the plasma drug concentration-time curve (AUC) reflects the actual body exposure to drug after administration of a dose of the drug and is expressed in mg*h/L. This area under the curve is dependant on the rate of elimination of the drug from the body and the dose administered.

How is AUC calculated?

AUC :Area under curve (AUC) is also known as c-statistics. Some statisticians also call it AUROC which stands for area under the receiver operating characteristics. It is calculated by adding Concordance Percent and 0.5 times of Tied Percent.

Where is AUC located?

How is area under the curve useful?

You can use the area under the curve to find the total distance traveled in the first 8 seconds. Since the quadratic is a curve you must choose the number of subintervals you want to use and whether you want right or left handed boxes for estimating. Suppose you choose 8 left handed boxes of width one.

How do you calculate AUC by hand?

You can divide the space into 2 parts: a triangle and a trapezium. The triangle will have area TPR*FRP/2 , the trapezium (1-FPR)*(1+TPR)/2 = 1/2 – FPR/2 + TPR/2 – TPR*FPR/2 . The total area is 1/2 – FPR/2 + TPR/2 . This is how you can get it, having just 2 points.
