Scalable Bayesian Disease Mapping Models for High-Dimensional Data.
bigDM
Scalable Bayesian disease mapping models (univariate and multivariate) for high-dimensional data using a divide and conquer approach.
Table of contents
The package
This package implements several (scalable) spatial and spatio-temporal Poisson mixed models for high-dimensional areal count data in a fully Bayesian setting using the integrated nested Laplace approximation (INLA) technique.
Below, there is a list with a brief overview of all package functions:
add_neighbour
Adds isolated areas (polygons) to its nearest neighbour.CAR_INLA
Fits several spatial CAR models for high-dimensional count data.clustering_partition
Obtain a spatial partition using the DBSC algorithm.connect_subgraphs
Merges disjoint connected subgraphs.divide_carto
Divides the spatial domain into subregions.MCAR_INLA
Fits several spatial multivariate CAR models for high-dimensional count data.mergeINLA
Merges inla objects for partition models.Mmodel_compute_cor
Computes between-disease correlation coefficients for M-models.Mmodel_idd
Implements the spatially non-structured multivariate latent effect.Mmodel_icar
Implements the intrinsic multivariate latent effect.Mmodel_lcar
Implements the Leroux et al. (1999) multivariate latent effect.Mmodel_pcar
Implements the proper multivariate latent effect.random_partition
Defines a random partition of the spatial domain based on a regular grid.STCAR_INLA
Fits several spatio-temporal CAR models for high-dimensional count data.
Installation
Installing Rtools44 for Windows
R version 4.4.0 and newer for Windows requires the new Rtools44 to build R packages with C/C++/Fortran code from source.
Install from CRAN
install.packages("bigDM")
Install from GitHub (development version)
# Install devtools package from CRAN repository
install.packages("devtools")
# Load devtools library
library(devtools)
# Install the R-INLA package
install.packages("INLA", repos=c(getOption("repos"), INLA="https://inla.r-inla-download.org/R/stable"), dep=TRUE)
# In some Linux OS, it might be necessary to first install the following packages
install.packages(c("cpp11","proxy","progress","tzdb","vroom"))
# Install bigDM from GitHub repositoy
install_github("spatialstatisticsupna/bigDM")
IMPORTANT NOTE: At least the stable version of INLA 22.11.22 (or newest) must be installed for the correct use of the bigDM package.
