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`.
