RMschur {RandomFields}R Documentation

Schur product

Description

The covariance function is

C(x)= M * φ(x)

where ‘*’ denotes the Schur product, i.e. elementwise multiplication

Usage

RMschur(phi, M,  diag, rhored, var, scale, Aniso, proj)

Arguments

phi

covariance function of class RMmodel.

M

constant n x n covariance matrix of the same size as multivariate model phi

diag,rhored

alternative way of passing M: diag is a vector of variances, rhored is a vector containing the correlations of lower triangle of the M

var,scale,Aniso,proj

optional arguments; same meaning for any RMmodel. If not passed, the above covariance function remains unmodified.

Value

RMschur returns an object of class RMmodel
