In joeguinness/GpGp: Fast Gaussian Process Computation Using Vecchia's Approximation
exponential_anisotropic3D_alt 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)
d_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 n rows and 3 columns.
Each row of locs is a point in R^3.
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,].
Functions
-
d_exponential_anisotropic3D_alt(): Derivatives of anisotropic Matern covariance
