Dear list, Is it possible to perform a spectral map analysis with SPSS? If not, some one knows a free program to do so. Many thanks, /Christian
I believe, but am not sure, that spectral map analysis is the same as correspondence analysis (dual scaling). It is certainly similar in that both spectral map analysis and correspondence analysis project variables and cases in a deduced dimensional space.
Every so often a procedure comes around that is the same but goes by different names. (e.g., correspondence analysis from Europe & dual scaling from Canada, and possibly a form of multidimensional scaling from the US). If you do no get closure from the responses on this list, I suggest you describe your data and problem on the Classification Society list. Mention that you would to use SPSS if possible. http://www.classification-society.org/csna/lists.html#class-l Art Art@DrKendall.org Social Research Consultants University Park, MD USA (Inside the Washington, DC beltway.)
