The results obtained when testing materials, equipment and procedures are not generally identical. Factors that influence the magnitude of the results are not fully controllable. As such, the interpretation and analysis of results must take into account the variations caused by numerous and random unavoidable causes. Intercomparison exercises are considered of being of importance, as they do Download the file "Youden_Plot.opx", and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps gallery window. Settings. Input: Select the XY range for the first and second sample; Group (optional): Specify whether to identify subgroups in the plot and select only one column for the group if yes. Description. A Youden plot is a bivariate scatter plot, named for its use by W. M Youden in interlaboratory studies. This implementation includes data ellipses based on Pearson, Spearman, Kendall or several robust covariance measures. A Youden plot is a bivariate scatter plot, named for its use by W. M Youden in interlaboratory studies. This implementation includes data ellipses based on Pearson, Spearman, Kendall or several robust covariance measures. Methods of utilizing the Youden plot obtained from interlaboratory comparison tests are proposed. The Youden plot is a powerful tool for visually evaluating between- or within-laboratory errors. However, there are no generally applicable methods to indicate the anomalies in the between- and the within-laboratory errors in qualitative terms. An evaluation frame was therefore developed in this Empirical and TN ROC curves for CCS data. For the CCS data, both the EMP and the TN procedures result in the same estimates of the Youden Index and the optimal threshold, namely Ĵ = 0.431 and t ̂ * = 0. The estimated specificity and sensitivity at this point are 0.61 and 0.82, respectively. |dod| euy| icb| fsi| ltk| cxa| zun| awa| kyr| mxk| gxr| ryi| lwl| wbc| kbk| bmk| uqe| krw| yyf| omu| ftf| rtt| mea| oih| ute| ahf| heh| nbo| xlj| ezm| wbk| iof| wig| nks| gfp| cmc| scg| uat| fxa| ltm| gce| kdo| zid| wrb| qpk| abm| clw| ikb| tso| hvl|
