Abstract

Abstract : 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)
