Hi Andrew, I don't have any experience in this area but I was intrigued by your question. Here is what I learned.
1, A bit of poking around turned up a thread on stats.stackexchange that mentions that "smallest space analysis" (SSA) is a special case of "multidimensional scaling" (MDS). See the thread here: https://stats.stackexchange.com/questions/82462/guttmans-smallest-space-analysis 2. The R package SMACOF implements some solutions for MDS. See the documentation "Multidimensional Scaling in R: SMACOF" available at https://mran.microsoft.com/snapshot/2018-05-13/web/packages/smacof/vignettes/smacof.pdf HTH, Eric On Wed, Sep 19, 2018 at 2:00 PM, Andrew <phaedr...@gmail.com> wrote: > Hi > > As part of my forensics psych course, we have been introduced to > Guttman's smallest space analysis (SSA).
