The Choice of Initial Configurations in Multidimensional Scaling: Local Minima, Fit, and Interpretability
Multidimensional scaling (MDS) algorithms can easily end up in local minima, depending on the starting configuration. This is particularly true for 2-dimensional ordinal MDS. A simulation study shows that there can be many local minima that all have an excellent model fit (i.e., small Stress) even...
