Matern.logLik.aniso: Log likelihood function for anisotropic Matern GP

In ashtonwiens/nonstationary: What the Package Does (One Line, Title Case)

Description

Log likelihood function for anisotropic Matern GP

Usage

Matern.logLik.aniso(
  pars = c(log(1.5), log(0.1), log(0.01), log(0.5), 0),
  grd,
  y,
  nu = 1
)

Arguments

pars	covariance parameters: range in x, Matern variance, white noise variance, range in y, and rotation angle
grd	a two columns matrix with the spatial locations of the data
y	the value of the response variable at the locations in grd
nu	a number > 0, the smoothness parameter

Value

the negative log likelihood
