We have been doing research on values. We let participants sort values (around 300 of them!) by 100 participants. We will do MDS analysis on the sorting results. However, we have problems how to set the matrix so we can use the data in SPSS. Could anybody can help us in this process. I read the examples, It helped but I have still problems. There is a mention about a program to get in data into matrix in this MDS examples. How I can reach the program.
