Accounting for Random Displacements of True GPS Coordinates of Data

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. Umut Altay, John Paige, Andrea Riebler, Geir-Arne Fuglstad (2024) . Umut Altay, John Paige, Andrea Riebler, Geir-Arne Fuglstad (2023) .

GeoAdjust

The R package GeoAdjust is constructed to implement empirical Bayesian geostatistical inference for DHS household survey data sets under positional uncertainty of household cluster centers.
