inla.spde2.matern.sd.basis {INLA}

R Documentation

Approximate variance-compensating basis functions

Description

Calculates an approximate basis for tau and kappa for an inla.spde2.matern model where tau is a rescaling parameter.

Usage

inla.spde2.matern.sd.basis(mesh, B.sd, B.range, method = 1,
                           local.offset.compensation = FALSE,
                           alpha = 2, ...)

Arguments

`mesh`	An `inla.mesh` object.
`B.sd`	Desired basis for log-standard deviations.
`B.range`	Desired basis for spatial range.
`method`	Construction method selector. Expert option only.
`local.offset.compensation`	If `FALSE`, only compensate in the average for the `tau` offset.
`alpha`	The model `alpha` parameter.
`...`	Additional parameters passed on to internal `inla.spde2.matern` calls.

Value

List of basis specifications

`B.tau`	Basis for `log(tau)`
`B.kappa`	Basis for `log(kappa)`

Intended for passing on to inla.spde2.matern.
