Biplot Display of Multivariate Matrices for Inspection of Data and Diagnosis by K. Ruben Gabriel( Book )

2 editions published in 1980 in English and held by 2 WorldCat member libraries worldwide

The biplot graphical display is introduced and its mathematical properties indicated. Its use for inspecting data matrices is illustrated for small and large matrices as well as for variance-covariance configurations and multivariate means of several samples. Its usefulness in diagnosing models is explained and illustrated by several examples requiring increasingly complex linear and harmonic models. Some comments are made on the relation to other multivariate displays. (Author)

Some comparisons of biplot display and pencil-and-paper E.D.A. methods by Christopher Cox( Book )

1 edition published in 1981 in English and held by 1 WorldCat member library worldwide

Multivariate data may be explored by a variety of methods. This paper considers some examples of alternative analyses by biplot display and by Tukey's pencil-and-paper EDA methods. It suggests that in using the biplot, a few displays usually suffice to reveal patterns in a pretty striking manner. When using EDA, on the other hand, one may require several stages of median polish, inspection of residuals, modelling, and re-expression. The biplot is more immediate: It allows one to see things at a glance
BGRAPH -- A Program for Biplot Multivariate Graphics. Version 1. User's Guide by Michael C Tsianco( Book )

1 edition published in 1981 in English and held by 1 WorldCat member library worldwide

This report is a user's manual for BGRAPH, an interactive, conversational program to perform multivariate graphics. The program generates 2- or 3-D graphical displays of biplots of data matrices factorized appropriately. These show various aspects of the biplot that have been found useful for visualizing data and for diagnosing models to fit data. It includes options for rotation, perspective and analglyph displays as well as concentration ellipses(oids) of subsets of points. BGRAPH is written in FORTRAN and is implemented on a DEC 10 under the TOPS 10 operating system. Graphic display is carried out through the system plot package of the NCAR graphics package. (Author)

Modeling Temperature Data: An Illustration of the Use of Biplots and Bimodels in Non-Linear Modeling( Book )

1 edition published in 1981 in English and held by 1 WorldCat member library worldwide

The paper describes a strategy for exploration and modeling of multivariate data. The data illustrated are temperatures at 50 North, Central and South American stations; the techniques rely heavily on lower rank approximation, biplot and binomial display, least squares fitting, and examination of residuals. The biplot/bimodel display is shown to reveal the relation of temperatures to various geographical features, (No new meteorological findings are claimed--the example is used mainly to illustrate the technique.) More strikingly, the bimodel shows an elliptical configuration of the markers for the different months. The paper shows how this ellipse implies a harmonic model for the temperatures themselves. This model makes good physical sense and its parameters are readily understood in meteorological terms. Some summary comments are made about the usefulness of biplots and bimodels for diagnosing models that may fit the data. (Author)
