param2.matern.orig {INLA}R Documentation

Parameter settings for inla.spde2.matern models.

Description

Construct parameter settings for inla.spde2.matern models.

Usage

param2.matern.orig(
  mesh,
  alpha = 2,
  B.tau = matrix(c(0, 1, 0), 1, 3),
  B.kappa = matrix(c(0, 0, 1), 1, 3),
  prior.variance.nominal = 1,
  prior.range.nominal = NULL,
  prior.tau = NULL,
  prior.kappa = NULL,
  theta.prior.mean = NULL,
  theta.prior.prec = 0.1
)

Arguments

mesh

The mesh to build the model on, as an fmesher::fm_mesh_2d() object, or other fmesher mesh supporting fmesher::fm_dof(), fmesher::fm_manifold_dim() and fmesher::fm_dof().

alpha

Fractional operator order, 0<\alpha\leq 2 supported. (\nu=\alpha-d/2)

B.tau

Matrix with specification of log-linear model for \tau.

B.kappa

Matrix with specification of log-linear model for \kappa.

prior.variance.nominal

Nominal prior mean for the field variance

prior.range.nominal

Nominal prior mean for the spatial range

prior.tau

Prior mean for tau (overrides prior.variance.nominal)

prior.kappa

Prior mean for kappa (overrides prior.range.nominal)

theta.prior.mean

(overrides ⁠prior.*⁠)

theta.prior.prec

Scalar, vector or matrix, specifying the joint prior precision for theta.
