In cocons: Covariate-Based Covariance Functions for Nonstationary Spatial Modeling

GetNeg2loglikelihoodTaper

Description

compute the negative 2 log likelihood based on theta

Usage

GetNeg2loglikelihoodTaper(theta, par.pos, ref_taper, locs, 
x_covariates, smooth.limits, cholS, z, n, lambda, safe = TRUE)

Arguments

theta	(numeric vector) a vector with parameters values.
par.pos	(list) par.pos list from getDesignMatrix.
ref_taper	(S4) spam object based on a compact-supported covariance function.
locs	(matrix) spatial location matrix.
x_covariates	(data.frame) design matrix.
smooth.limits	(numeric vector) smooth.limits.
cholS	(S4) Cholesky object from spam.
z	(numeric vector) a vector of observed values.
n	(numeric) dim(z)[1].
lambda	(numeric) regularization parameter.
safe	(TRUE/FALSE) if TRUE returns a large pre-defined value under Cholesky errors. Default TRUE.
