To interpret the biplot, it is necessary to know which points—usually variables—are the ones that are important contributors to the solution, especially when there are many variables involved. This information can be calculated separately as part of the biplot's numerical results, but this means that a table has to be consulted along with the graphical display. We propose a new scaling of the display, called the contribution biplot, which incorporates this diagnostic information directly into…

Biplot geometry underlies many classical multivariate procedures, such as principal component analysis, simple and multiple correspondence analysis, discriminant analysis, and other variants of dimension reduction methods such as log‐ratio analysis.

A weighted Euclidean distance that approximates any distance or dissimilarity measure between individuals that is based on a rectangular cases-by-variables data matrix is constructed, inspired by the distance functions used in correspondence analysis and in principal component analysis of standardized data.

An alternative scaling of the correspondence analysis solution, the contribution biplot, is proposed as a way of displaying the results in order to avoid the problem of outlying and low contributing rare objects.

Abstract In multiple correspondence analysis, both individuals (observations) and categories can be represented in a biplot that jointly depicts the relationships across categories and individuals,
A simple solution is proposed, consisting of the estimation of a weighted Euclidean distance that optimally approximates the dissimilarities, to extend the classical approach to ordination to any non-Euclidean or nonmetric dissimilarity.
This essay considers CA and taxicab CA as a stepwise Hotelling/Tucker decomposition of the cross-covariance matrix of the row and column categories into four quadrants and reviews the notion of quality/quantity in multidimensional data analysis as discussed by Benzécri.
