Description of a computer program for analyzing multivariate spatially distributed data

Abstract--This paper gives a detailed escription ofa program for the factor analysis of multivariate data from samples taken in a physical environment. The spatial correlation of the samples is represented by a model of nested spatial structures. The correlations of the variables are summarized by performing a principal component analysis on the coefficients of the spatial structures. The result is a linear model of the coregionalization that can be used for factorial kriging, conditional simulation, and cokriging. The program could be written for a microcomputer connected to a mainframe
