多维排列 (Multidimensional scaling,MDS)是可视化多变量样品(如多个物种丰度、多个基因表达)相似性水平的一种方法。其基于距离矩阵进行一系列的排序分析。 经典的MDS (CMDS)分析就是前面提到的PCoA分析,也称为度量性MDS分析。而与之相对的是非度量多维排列 (Non-metric multidimensional scaling,NMDS)。

多维排列（Multidimensional scaling, MDS）作为一种可视化工具，适用于展现多变量样品（如物种丰度、基因表达）之间的相似性水平。经典MDS（CMDS）分析即为PCoA，属于度量性MDS分析，而非度量多维排列（Non-metric multidimensional scaling, NMDS）则是一种更为灵活的非度量性方法。NMDS关注的是相异矩阵或距离...
其中，非度量NMDS (Non-metric Multidimensional Scaling)尤其在处理缺失数据和多样本分析时表现出色，它关注样品的排序而非严格的距离测量。NMDS通过秩矩阵进行降维，弱化距离的绝对值，聚焦于样品间的相对位置，适合定性、定量和半定量数据的分析。目标是清晰地展示样品间的联系，解读分布模式和梯度信息。评估...

ence data can be subjected to a multidimensional scaling analysis as well. This case involves restructuring the data in a square symmetric .n Cm/ .n Cm/ matrix with empty blocks on the diagonal and the preference data inserted in the off-diagonal part (see e.g., Borg & Groenen, 1997, ...
