How to reproduce SAS Multidimensional Scaling (MDS)
I am doing nonmetric multidimensional scaling using both SAS and JMP. My input for JMP is an n*n distance matrix (or dissimilarity matrix ). I was following the steps: Analyze-->Multivariate methods-->Multidimensional scaling and set the number of dimensions to 5. In SAS, I was using the proc mds procedure. My input matrix is the same lower triangle dissimilarity matrixproc mds data=my_matrix lev...
