I just want to ask about the MDS. Below is the subcategory of the Multidimensional Scaling topic.

Multidimensional Scaling

  1. Metric and Non-Metric Models
  2. Methods of "Two-Way" Multidimensional Scaling (MDS)

I was tasked to report the second sub-topic of MDS which is the Methods of "Two-Way" Multidimensional Scaling. I don't have any idea about this topic actually, but when I try to surf through the internet, I found out one book which is all about Multidimensional Scaling. The problem is that I can't find the topic. But, I observed that there is this Section of Chapters entitled MDS and Related Methods consisting of chapters entitled Procrustes Procedures, Three-Way Procrustean Models, Three-Way MDS Models, Modeling Asymmetric Data, and Methods Related to MDS.

I know this could not be the Methods of "Two-Way" Multidimensional Scaling (MDS). I'm not sure.

I just want a help on the description of the Methods of "Two-Way" Multidimensional Scaling (MDS), or what does it talks about? or what are the possible sub-topics to tackle if any. Your help would greatly be appreciated.

I don't know about "two-way multidimensional scaling" but googling gives this: Two-Way Multidimensional Scaling: A Review and
Classical Metric Multidimensional Scaling

(But my impression from googling is just that this "two-way" thingy is an alternative name for what we just call MDS, referring to the fact that the input data usually is a matrix, thus "two-way". Evidence for this is the following link:

Three-Way Multidimensional Scaling

which gives some generalizations.
