inla.spde.precision: Precision matrices for SPDE models

In inbo/INLA: Full Bayesian Analysis of Latent Gaussian Models using Integrated Nested Laplace Approximations

Description

Calculates the precision matrix for given parameter values based on an inla.spde model object.

Usage

inla.spde.precision(...)

## S3 method for class 'inla.spde2'
inla.spde.precision(spde,
                    theta = NULL,
                    phi0 = inla.spde2.theta2phi0(spde, theta),
                    phi1 = inla.spde2.theta2phi1(spde, theta),
                    phi2 = inla.spde2.theta2phi2(spde, theta), ...)
inla.spde2.precision(spde,
                     theta = NULL,
                     phi0 = inla.spde2.theta2phi0(spde, theta),
                     phi1 = inla.spde2.theta2phi1(spde, theta),
                     phi2 = inla.spde2.theta2phi2(spde, theta), ...)

## For deprecated inla.spde1 models:
## S3 method for class 'inla.spde1'
inla.spde.precision(spde, ...)
inla.spde1.precision(spde, ...)

Arguments

spde	An inla.spde object.
theta	The parameter vector.
phi0	Internal parameter for a generic model. Expert option only.
phi1	Internal parameter for a generic model. Expert option only.
phi2	Internal parameter for a generic model. Expert option only.
...	Additional parameters passed on to other methods.

Value

A sparse precision matrix.
