Candidates need to have high school diplomas or the equivalent; they also need to be at least 21 years old and be U.S. citizens.
Step 3. Use the equation of the calibration curve to adjust measurements taken on samples with unknown values. Substitute the measured value as x into the equation and solve for y (the true value). In the example from step 2, y = 1.05x + 0.2. Thus, a measured value of 75.0, for example, would adjust to y = 1.05(75) + 0.2 = 78.9.
Section 5 we present lift chart and describe the interrelation between area under the ROC. curve and lift chart curve. In Section 6 we introduce the calibration plot and show how. ROC curve, lift chart and the area under both curves can be derived from the calibration. 1Department of Knowledge Technologies, JoËzef Stefan Institute, Slovenia; miha.vuk@ijs.si. 2University of Ljubljana, Faculty of Computer and Information Science, Slovenia; tomaz.curk@fri.uni-lj.si.
