There really only one small difference, but that difference means you need to know what you're doing if you're going to use MDS effectively.

null | null | null | null | null | StatQuest: MDS and PCoA in R | 2017-12-18 | Doing MDS (multi-dimensional scaling) and PCoA (principal coordinate analysis) is pretty easy with the cmdscale() option. However, there are some tricks to it and I show you how to create a distance matrix using a non-standard distance metric.
