In INLAtools: Functionalities for the 'INLA' Package

Defines a GMRF model to be used with the C interface for INLA as a latent model.

Description

This prepare data for the C type to organize data needed for building latent models which are characterized from given model parameters \theta and the the following model elements.

• graph to define the non-zero precision matrix pattern. only the upper triangle including the diagonal is needed. The order should be by line.

• Q vector where the

  • first element (N) is the size of the matrix,

  • second element (M) is the number of non-zero elements in the upper part (including) diagonal

  • the remaining (M) elements are the actual precision (upper triangle plus diagonal) elements whose order shall follow the graph definition.

• mu the mean vector,

• initial vector with

  • first element as the number of the parameters in the model

  • remaining elements should be the initials for the model parameters.

• log.norm.const log of the normalizing constant.

• log.prior log of the prior for the model parameters.

See details in INLA::cgeneric()

Usage

cgeneric(model, ...)

Arguments

model	object class for what a cgeneric method exists. if it is a character, a specific function will be called, for example cgeneric("iid", ...") calls cgeneric_iid(...), see cgeneric_iid() and cgeneric_generic0().
...	additional arguments passed on to methods

Value

named list of cgeneric class containing the named list f that contain model (a character always equal to cgeneric), n (integer) and cgeneric as a named list that contains the data needed to define the model. Each element on ...$f$cgeneric is also a named list containing ints, doubles, characters, matrices and smatrices.
