Nonlinear Principal. Components Analysis: Introduction and Application. This chapter provides a didactic treatment of nonlinear (categorical) principal components referred to as nonlinear principal components analysis, has been developed. A first version . In summary, although ordinal variables display more structure
Summary. Although linear principal component analysis (PCA) originates from the work of Sylvester [67] and Pearson [51], the development of nonlinear coun- terparts has only received attention from the 1980s. Work on nonlinear PCA, or. NLPCA, can be divided into the utilization of autoassociative neural networks,.
Abstract Principal components analysis (PCA) is a commonly used descriptive multivariate method for handling quantitative data and can be extended to deal with mixed measurement level data. For the extended PCA with such a mixture of quan- titative and qualitative data, we require the quantification of qualitative data in
29 Nov 2017 Full-text (PDF) | The authors provide a didactic treatment of nonlinear (categorical) principal components analysis (PCA). This method is the nonlinear equivalent of standard PCA and reduces the observed variables to a number of uncorrelated principal components. The most important advantages of n

21 Dec 2017 Full-text (PDF) | We discuss several forms of Nonlinear Principal Compo-nent Analysis (NLPCA) that have been proposed over the years: Linear PCA with optimal scaling, aspect analysis of correlations, Guttman's MSA, Logit and Probit PCA of binary data, and Logistic Homogeneity Analysis. They are co

We shall not dwell on each and every one of them, but we consider the one most relevant for the nonlinear general- izations of PCA we want to discuss. Our de?nition of PCA is based on approximating the elements of the data
