meshCountry

Creates a constrained refined Delaunay triangulation mesh based on the country borders.

The purpose is to account for the random displacements
(jittering) of true survey household cluster center coordinates in geostatistical
analyses of Demographic and Health Surveys program (DHS) data. Adjustment for
jittering can be implemented either in the spatial random effect, or in the
raster/distance based covariates, or in both. Detailed information about the methods
behind the package functionality can be found in our two papers.
