Covariance matrix for the bivariate Gaussian common component geostatistical model

Covariance matrix for the bivariate Gaussian common component geostatistical model or its inverse, and optionally the determinant of the matrix.

Keywords
spatial
Usage
varcovBGCCM(dists.obj, cov0.pars, cov1.pars, cov2.pars,
            cov0.model = "matern", cov1.model = "matern",
            cov2.model = "matern", kappa0 = 0.5, kappa1 = 0.5,
            kappa2 = 0.5, scaled = TRUE, inv = FALSE, det = FALSE)
Arguments
dists.obj

a vector with distance values

cov0.pars

covarianve paremeter values for the common component

cov1.pars

covariance parameter for the individual structure of the first variable

cov2.pars

covariance parameter for the individual structure of the second variable

cov0.model

character indicating a valid correlation model

cov1.model

character indicating a valid correlation model

cov2.model

character indicating a valid correlation model

kappa0

scalar

kappa1

scalar

kappa2

scalar

scaled

logical

inv

logical. If TRUE the inverse of the covariance matrix is returned instead.

det

logical. Optional, if TRUE the logarithm of the detarminant of the covariance matrix is returned as an attribute.

Value

A matrix which is the covariance matrix for the bivariate Gaussian common component geostatistical model or its inverse if inv=TRUE. If det=T the logarithm of the determinant of the matrix is also returned as an attribute named logdetS.

Warning

This is a new function and still in draft format and pretty much untested.
