Statistical Details for the Multidimensional Scaling Platform
JMP uses a quasi Newton optimization method to minimize the Stress function to determine the MDS coordinates. This minimization leads to a set of coordinates in a predetermined number of dimensions that minimize the derived proximity measures for each pairwise set of the dimensions. When the data is ordinal, monotonic regression is used. Otherwise, standard least squares regression is used.
