MDS with ranking data (and transformation)
...ess such a transformation would also allow me to do clusteranalysis? - But how to do it??? Anyways: what I have done so far is to compute a 10*10 matrix in a spreadsheet application. I do this by countif(range_choice1=philospher1)*10 for each philospher. In ?range_choice2? I multiply by 9, and in ?range_choice3? I multiply with 8 etc. The corresponding matrix I import to r and do dist(t(matrix) and then I use cmdscale$points to draw a plot. It looks nice but I am almost sure I'm doing it wrong. And I would certainly like not having rely on a spreadsheet. So my question is: how to transform the data...
