Hello,
I would like to know more about the MDS used for the "Code Map" function in MaxQDA Visual Tools. In the MaxQDA Manual, it states that the Code Map is "based on classical MDS". This process requires generating a dissimilarity matrix from the Codes Relations Browser, and then converting that into a distance matrix.
Can you explain more about what type of method is used in this ordination, for example PCoA or NMDS? And which method is used to create the distance matrix, e.g. is it Bray-Curtis or Gower's distance? Also, is it possible to generate stressplots or some kind of measure of goodness of fit for these ordinations?
This would really help, as I am trying to understand why I find differences in mapped codes between the Code Maps and other ordinations I have made with my data.
Thank you!
