Nonlinear statistical mapping

Multidimensional scaling is a nonlinear statistical mapping technique that can be used in data reduction and compression. Its use by the chemical community appears to be virtually nonexistent, and we merely refer the reader to the text by Schiffman et al. ... 

Unsupervised multivariate statistical methods [CA, principal components analysis, Kohonen s self-organizing maps (SOMs), nonlinear mapping, etc.], which perform spontaneous data analysis without the need for special training (learning), levels of knowledge, or preliminary conditions. 

Several other statistical tools based on linear and nonlinear methods have been used to analyze array data, including self-organizing maps, k-means clustering, and principal component analysis (Tamayo et al., 1999 Ben-Dor et al., 1999). Each of these tools has merit, and software for some of these is publicly available. However,...
