    Conceptual difference between STRESS and SSTRESS

    I am studying the difference between STRESS and SSTRESS optimization functions in the context of multidimensional scaling. I have encountered this definition of optimization criteria for the SSTRESS: My question is : why using squared estimators and squared distances (in MDS or in general)...

    Multidimensional scaling with threshold values

    Hi, I have a matrix of L2 (euclidean) distances and would like to perform multidimensional scaling in order to retrieve the positions of the points which generated this set of distances. I say "retrieve" because I know that these distances were actually generated by real points (plus some...
