Dear Listmembers, I would like to do a MDS with a 400X400 square, symetric matrix of (dis)similaritys. Most MDS-Software is limited to a much smaller amount of variables though. I have been told, that SAS might be able to process the analyis I need, but this is quite inconvenient for me in terms of access to the software, hardware-requirements etc. Could anybody tell me, if there is a stand-alone program that can do MDS (preferably nonmetric) with a matrix of that size? Thanks a lot for your help, dirk P.S: My Matrix is not suitable for factor analysis and clustering does not produce the results I need.
