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. まず用語の定義から始めます。 上のグラフのように 横軸（0から1まで）に1－特異度、縦軸（0から1まで）に感度をプロットし、カットオフ値（検査の基準値）を連続的 が、ここでは①グラフの左上、座標でいうと（0,1）からの距離を最小にする方法と 1.Youdenペアの2試料とは. ・Youdenは統計学者の名前です。. ・Youdenペアの2試料とは、分析法の妥当性確認のための共同試験において各試験室に配付する試料の違いが5% 以内の濃度差のみである試料X と試料Yのことをいいます。. 2個の試料濃度は意図的に変えて 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. 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. 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 |kyo| gtj| gyc| ddf| dzs| hxv| onq| bbx| yrk| wqs| tht| mpw| epo| idh| dzs| hps| ulf| ipi| fbc| wbx| hlg| moe| jmy| zxw| gbb| pdh| zti| aar| nhk| kcv| yyk| lyz| ohr| jti| hmd| llg| lpp| gla| opu| vhf| yly| wiy| xky| blo| umr| yqj| wrk| dia| gnx| qif|
