The concept of robustness in scaling and unfolding analyses

Dimitar Atanasov

A variety of techniques in the area of multivariate data analysis arecovered by the procedures for multidimensional scaling.

To improve the performance of these analyses, the ideas of robuststatistics can be applied. In this way estimates stable to thepresence of outliers can be obtained.

A robust modification of unidimensional unfolding andmultidimensional scaling are considered using the technique ofd-fullness.
