rspde.matern.intrinsic {rSPDE} | R Documentation |
Intrinsic Matern rSPDE model object for INLA
Description
Creates an INLA object for a stationary intrinsic Matern model. Currently, alpha is fixed to 2 and beta is fixed to 1.
Usage
rspde.intrinsic.matern(
mesh,
alpha = 2,
mean.correction = FALSE,
prior.lkappa.mean = NULL,
prior.ltau.mean = 1,
prior.lkappa.prec = 0.1,
prior.ltau.prec = 0.1,
start.ltau = NULL,
start.lkappa = NULL,
true.scaling = TRUE,
diagonal = 0,
debug = FALSE,
shared_lib = "detect",
...
)
Arguments
mesh |
The mesh to build the model. It can be an |
alpha |
Smoothness parameter, need to be 1 or 2. |
mean.correction |
Add mean correction for extreme value models? |
prior.lkappa.mean |
Prior on log kappa to be used for the priors and for the starting values. |
prior.ltau.mean |
Prior on log tau to be used for the priors and for the starting values. |
prior.lkappa.prec |
Precision to be used on the prior on log kappa to be used for the priors and for the starting values. |
prior.ltau.prec |
Precision to be used on the prior on log tau to be used for the priors and for the starting values. |
start.ltau |
Starting value for log of tau. |
start.lkappa |
Starting value for log of kappa. |
true.scaling |
Compute the true normalizing constant manually? Default |
diagonal |
Value of diagonal correction for INLA stability. Default 0. |
debug |
INLA debug argument |
shared_lib |
Which shared lib to use for the cgeneric implementation? If "detect", it will check if the shared lib exists locally, in which case it will use it. Otherwise it will use INLA's shared library. If "INLA", it will use the shared lib from INLA's installation. If 'rSPDE', then it will use the local installation (does not work if your installation is from CRAN). Otherwise, you can directly supply the path of the .so (or .dll) file. |
... |
Only being used internally. |
Value
An INLA model.
