Multidimensional scaling plot: point grouping/clustering
I'm using multidimensional scaling on a 91 x 91 distance matrix. When the 2D MDS plot is displayed, the points are plotted using various different symbols and colors assigned by JMP, evidently clustering points togethers based on their proximity in the multidimensional distance space (see attached screenshot). Questions: What is the criterion that JMP is using to decide how to group or cluster poi...
