Evaluate log-lik

Description

Evaluate the log-likelihood for a given set of parameters - No nugget + profile likelihood

Usage

singl_log_lik_nn(
  theta,
  .dt,
  dists,
  npix,
  model,
  nu = NULL,
  tr = NULL,
  kappa = 1,
  mu2 = 1.5,
  apply_exp = FALSE
)

Arguments

theta

a scalar for the \phi parameter.

.dt

a numeric vector containing the variable Y.

dists

a list of size three. The first containing the distance matrices associated with the regions where Y was measured, the second for the distance matrices associated with X, and the last containing the cross-distance matrices.

npix

a integer vector containing the number of pixels within each polygon. (Ordered by the id variables for the polygons).

model

a character indicating which covariance function to use. Possible values are c("matern", "pexp", "gaussian", "spherical", "cs", "gw", "tapmat").

nu

\nu parameter. Not necessary if mode is "gaussian" or "spherical"

kappa

\kappa \in \{0, \ldots, 3 \} parameter for the GW cov function.

mu2

the smoothness parameter \mu for the GW function.

apply_exp

a logical indicating whether the exponential transformation should be applied to variance parameters. This facilitates the optimization process.

Details

Internal use.

Value

a scalar representing -log.lik.
