The Youden pH Meter
Sørensen used a slide-wire potentiometer to make his pH measurements. Here a known potential is applied to counterbalance the potential of the hydrogen cell (i.e. the hydrogen electrode plus the counter electrode) and to reduce its current output to zero, at which point the value of the applied counter-potential is equal to that of the cell potential. Since the point of balance is indicated by...
متن کاملYouden Plot in Dimensions Measurement
The capability of the dimensions measurement by ten appraisers of ten samples for Charpy Vnotch pendulum impact test was evaluated by Youden plot, analysis of measurement uncertainties, Measurement Systems Analysis (MSA), %P/T, Z-score, Mandel’s statistics and ttest. The group of “better” appraisers given by Youden plot was validated by majority of other methods.
متن کاملStatistical Inferences for the Youden Index
In diagnostic test studies, one crucial task is to evaluate the diagnostic accuracy of a test. Currently, most studies focus on the Receiver Operating Characteristics Curve and the Area Under the Curve. On the other hand, the Youden index, widely applied in practice, is another comprehensive measurement for the performance of a diagnostic test. For a continuous-scale test classifying diseased a...

متن کاملImproved Confidence Intervals for the Youden Index
The Youden Index is a summary measurement of the receiver operating characteristic (ROC) curve for the accuracy of a diagnostic test with ordinal or continuous endpoints. The bootstrap confidence interval based on the adjusted proportion estimate was shown to have satisfactory performance among the existing confidence intervals, including the parametric interval via the delta method. In this ar...
