%description
Multidimensional scaling (MDS) functions for various tasks that are beyond
the beta stage and way past the alpha stage. Currently, options are
available for weights, restrictions, classical scaling or principal
coordinate analysis, transformations (linear, power, Box-Cox, spline,
ordinal), outlier mitigation (rdop), out-of-sample estimation (predict),
negative dissimilarities, fast and faster executions with low memory
footprints, penalized restrictions, cross-validation-based penalty
selection, supplementary variable estimation (explain), additive constant
estimation, mixed measurement level distance calculation, restricted
classical scaling, etc. More will come in the future. References. Busing
