getINLAParameters: Extracting parameters from INLA MBG models

In SEEG-Oxford/seegMBG: Streamlined Model-Based Geostatistics Functions for the SEEG Research Group

Description

Given a fitted inla object for a spatial or spatio-temporal geostatistical model, extract model parameters either from the maximum a posterior parameter set, or as samples from the predictive posterior.

Usage

getINLAParameters(inla, method = c("sample", "MAP"), n = 1)

Arguments

inla	a fitted inla object with fixed effects terms and a spatial or spatio-temporal random effect model. If method = "sample" then inla must have been fitted with the argument control.compute = list(config=TRUE).
method	whether to draw n samples from the predict posterior (if method = "sample", the default) or to make predictions at the maximum a posteriori estimates of the model parameters (if method = "MAP"). If method = "sample" then inla must have been fitted with the argument control.compute = list(config=TRUE).
n	if method = "sample", the number of samples to draw from the predictive posterior.

Value

An object of class params, being a list with three elements:

• params parameters

• names parameter names

• indices

  • fixed_idx index to fixed effect parameters in params and names

  • spatial_idx index to spatial random effect parameters in params and names

  • hyper_idx index to hyperparameters in params and names
