Biplots for matched two-way tables
نویسندگان
چکیده
— This paper is an investigation into the exploratory analyses of matched two-way tables and their biplot visualizations. In doing so, we revisit the singular value decomposition of real and complex matrices. It is shown how standard methods, initially derived for the analysis of square tables, extend to this more general setting. The modeling interpretation of these biplots is also elicited.

Visualization of Process Data with Biplots
In this paper the methodology of biplots is introduced as a means for monitoring the behaviour of process systems. This sophisticated methodology allows for the projection of high-dimensional data to a low-dimensional subspace that can be visualised by a human operator. The projections are highly graphical in nature, and rich in information regarding variation in process variables, correlations...

In this paper, a general theory of canonical coordinates is developed for reduction of dimensionality in multivariate data, assessing the loss of information and plotting higher dimensional data in two or three dimensions for visual displays. The theory is applied to data in two way tables with variables in one category and samples (individual or populations) in the other. The method is applica...
متن کاملModi...ed biplots for enhancing two-class discriminant analysis
When applied to discriminant analysis (DA) biplot methodology leads to useful graphical displays for describing and quantifying multidimensional separation and overlap among classes. The principles of ordinary scatterplots are extended in these plots by adding information of all variables on the plot. However, we show that there are fundamental di¤erences between two-class DA problems and the c...

متن کاملPartial Association Components in Multi-way Contingency Tables and Their Statistiical Analysis
In analyses of contingency tables made up of categorical variables, the study of relationship between the variables is usually the major objective. So far, many association measures and association models have been used to measure the association structure present in the table. Although the association measures merely determine the degree of strength of association between the study varia...
