Score plots of PLS-DA distinguishing between the microbial community data of controls and NASH patients.Vincent, WaiSun Wong
PCA-DA (MarkerView) and PLS-DA (MetaboAnalyst) score plots of discriminant analysis. Group labels: P = 1 and 0, PB = 2 and 1, PM = 3 and 2, PMB = 4 and 3.Fabiola, G. ...
OPLS-DA loading plots for different mulberry cultivars The metabolites with loadings that were distant from the origin on the OPLS-DA-loading plots were inferred to make the greatest contribution to class separation. Organic acids, lipids, and flavonols were major contributors to the separation among...
但是,你可以使用 Origin 来绘制 PLS-DA 分析的结果。例如,如果你在 R、MATLAB 或其他软件中进行了 PLS-DA 分析,你可以将得到的数据(如得分、负荷、VIP 分数等)导出到 Origin 中,然后利用 Origin 强大的图形绘制功能来创建高质量的图表,如得分图(score plots)或负荷图(loading plots)。
Furthermore, we advocate against the use of PLSDA score plots for inference of class differences.doi:10.1007/s11306-007-0099-6Johan A. WesterhuisHuub C. J. HoefslootSuzanne SmitDaniel J. VisFerdi A. van DorstenSpringer USMetabolomics
For example, the F1 score will be necessarily low, while accuracy and specificity will be extremely high. When the number of noise features is low, precision could be artificially inflated. However, this is not likely in real experiments. Graphs are shown as 3D plots where the z axis ...

另外，PLS-DA和OPLS-DA所构建的分类模型中的载荷图可用于衡量各代谢物组分对样本分类判别的影响强度和解释能力，辅助标志代谢物的筛选。 ## 实例解读 OPLS-DA loading plots for different mulberry cultivars 该数据是通过液相色谱-高分辨率质谱(LC-HRMS)来研究年龄、体重指数(bmi)和性别对尿液中代谢物...
