exponential_anisotropic3D_alt {GpGp} | R Documentation |
Geometrically anisotropic exponential covariance function (three dimensions, alternate parameterization)
Description
From a matrix of locations and covariance parameters of the form (variance, B11, B12, B13, B22, B23, B33, smoothness, nugget), return the square matrix of all pairwise covariances.
Usage
exponential_anisotropic3D_alt(covparms, locs)

Arguments
covparms |
A vector with covariance parameters in the form (variance, B11, B12, B13, B22, B23, B33, smoothness, nugget) |
locs |
A matrix with |
Value
A matrix with n
rows and n
columns, with the i,j entry
containing the covariance between observations at locs[i,]
and
locs[j,]
.
