Quantification of intrinsic quality of a principal dimension in correspondence analysis and taxicab correspondence analysis

  title={Quantification of intrinsic quality of a principal dimension in correspondence analysis and taxicab correspondence analysis},
  author={Vartan Choulakian},
Collins(2002, 2011) raised a number of issues with regards to correspondence analysis (CA), such as: qualitative information in a CA map versus quantitative information in the relevant contingency table; the interpretation of a CA map is difficult and its relation with the % of inertia (variance) explained. We tackle these issues by considering CA and taxicab CA (TCA) as a stepwise Hotelling/Tucker decomposition of the cross-covariance matrix of the row and column categories into four quadrants…

Some notes on Goodman's marginal-free correspondence analysis

In his seminal paper Goodman (1996) introduced marginal-free correspondence analysis ; where his principal aim was to reconcile Pearson correlation measure with Yule’s association measure in the

Notes on Correspondence Analysis of Power Transformed Data Sets

We prospect for a clear simple picture on CA of power transformed or the Box-Cox transformed data initiated since 2009 by Grenacre. We distinguish two types of data sets : strictly positive and with

On the choice of weights in aggregate compositional data analysis

It is shown that in the aggregate case, the under-lying given data form a paired data sets composed of responses and qualitative covariates ; this fact helps to propose two approaches for analysis-visualization of data named log interaction of aggregates and aggregate of log interactions.



Taxicab Correspondence Analysis of Sparse Contingency Tables

Visualization and interpretation of contingency tables by correspondence analysis (CA), as developed by Benzecri, has a rich structure based on Euclidean geometry. However, it is a well established

Distributional Equivalence and Subcompositional Coherence in the Analysis of Compositional Data, Contingency Tables and Ratio-Scale Measurements

The weighted log-ratio methodology is used here to visualize frequency data in linguistics and chemical compositional data in archeology and is theoretically equivalent to “spectral mapping”, a multivariate method developed almost 30 years ago for displaying ratio-scale data from biological activity spectra.

Taxicab Correspondence Analysis of Ratings and Rankings

This paper provides necessary and sufficient conditions for TCA of Ynega or YD so that the first factor score is an affine function of the sum score of the ratings; and, if this is true for a dataset, then following Cox, suggests the use of thesum score of ratings either to reduce the Q ratings into a single index, or to summarize the underlying latent variable.

TCA and TLRA: A comparison on contingency tables and compositional data

A novel index named the intrinsic measure of the quality of the signs of the residuals (QSR) for the choice of the preprocessing, and consequently of the method of Correspondence analysis (CA) is introduced.

Contribution Biplots

A new scaling of the display is proposed, called the contribution biplot, which incorporates diagnostic information directly into the display itself, showing visually the important contributors and thus facilitating the biplot interpretation and often simplifying the graphical representation considerably.

Relations Between Two Sets of Variates

Concepts of correlation and regression may be applied not only to ordinary one-dimensional variates but also to variates of two or more dimensions. Marksmen side by side firing simultaneous shots at

Globally Homogenous Mixture Components and Local Heterogeneity of Rank Data

The traditional methods of finding mixture components of rank data are mostly based on distance and latent class models; these models may exhibit the phenomenon of masking of groups of small sizes;

Taxicab Correspondence Analysis

Taxicab correspondence analysis is based on the taxicab singular value decomposition of a contingency table, and it shares some similar properties with correspondence analysis. It is more robust than
