Abstract

A portable program MATCORS, for correspondence analysis is presented. To help understand the correspondence analysis method and computer algorithm, a detailed matrix algebraic description is used. Various diagnostic results are provided in the program to aid in interpreting the results, for example relative and absolute contributions, error profiles, and supplementary elementary projections. A series of graphs generated by this program is helpful for the analysis of the results. High-quality graphs are produced easily because the program operates withinthe user-friendly Matlab environment. Applications to soil sample data and precipitation data sets are given to verify and demonstrate thiscomputer program.
