stModel.precision {INLAspacetime}

Spacetime precision matrix.

Description

To build the the precision matrix for a spacetime model given the temporal and the spatial meshes.

Usage

stModel.precision(smesh, tmesh, model, theta, verbose = FALSE)

Arguments

smesh

a mesh object over the spatial domain.

tmesh

a mesh object over the time domain.

model

a string identifying the model. So far we have the following models: '102', '121', '202' and '220' models.

theta

numeric vector of length three with log(gamma_s, gamma_t, gamma_e).

verbose

logical to print intermediate objects.

Value

a (sparse) precision matrix, as in Lindgren et. al. (2023)
