I would like to do a Guttman Lingoes Smallest Space Analysis (SSA), which is a multidimensional scaling (MDS) technique. Does SPSS offer SSA?
Resolving The Problem
The Guttman-Lingoes technique, Smallest Space Analysis (SSA),can be performed in the PREFSCAL procedure, which was introduced to the Categories module in SPSS 14. SSA is not available in the multidimensional scaling routines ALSCAL (Base module) or PROXSCAL (Categories module), so SSA was not available in SPSS versions prior to Release 14.
