Example of finding an area that extends from minus infinity (∞) to a point to the right of the mean:To find the area under the normal curve, you must know how many standard deviations that point is to the right of the mean. Then the area under the normal curve can be read directly...
Areas under the Normal Curve A Z-score is a measurement of how far away a point is from the mean in terms of standard deviations. It is calculated by subtracting the value of the mean from the value of the point in question, then dividing by the standard deviation of the set. If you...

The curve y = f(x), completely above x-axis. Shows a "typical" rectangle, Δx wide and y high.[NOTE: The curve is completely ABOVE the x-axis].When Δx becomes extremely small, the sum of the areas of the rectangles gets closer and closer to the area under the curve. If it ac...
To make this decision, areas under the receiver operating curves (AROCs), sometimes called c-values, are widely used. As indicated by its name, AROC is the area under the ROC curve, that is the curve obtained by plotting the true positive rate (Sensitivity) against the false positive rate...
area over the lymphocyte curvearea under the lymphocyte curvecytomegalovirus reactivationBackground: We retrospectively compared the impact of the areas over and under the lymphocyte curve (L_AOC vs L_AUC) on cytomegalovirus (CMV) reactivation after allogeneic hematopoietic stem cell transplantation (HSCT...
Comparing areas under the ROC curve (AUC) is a popular approach to compare prognostic biomarkers. The aim of this manuscript is to present an efficient method to control the family﹚ise error rate when multiple comparisons are performed. We suggest to combine the max‐t test and the closed ...
Objective : The extrapolated area under the concentration–time curve (AUC 0–∞ ) for any drug is considered by operating guidelines as the primary parameter related to the extent of absorption in single-dose bioavailability and bioequivalence trials. Not more than 20% should be added to the ex...

In the UK patients, MIF, DJ-1 and CEA generated areas under the ROC curve of 0.62, 0.52 and 0.54, respectively (Figure 4). Logistic regression was used to determine if the diagnostic utilities of MIF, DJ-1 and CEA could be used in combination. Model selection and Wald chi-squared test...
