EgoCor: an R package to fit exponential semi-variograms to model the local spatial correlation structure of health outcomes
As an alternative to using administrative areas for the evaluation of
small-area health inequalities, Sauzet et al suggested to take an ego-centred
approach and model the spatial correlation structure of health outcomes at
individual level. Existing tools for the analysis of spatial data in R may
appear too complex to non-specialists which may limit the use of the approach.
We present the R package EgoCor which offers a user-friendly interface
displaying in one function a range of graphics and tables of parameters to
facilitate the decision making about which exponential parameters fit best
either raw data or residuals. This function is based on the functions of the R
package gstat. Moreover, we implemented a function providing the measure of
uncertainty proposed by Dyck and Sauzet. With the R package EgoCor the
modelling of spatial correlation structure of health outcomes with a measure of
uncertainty is made available to non specialists.Comment: Keywords: R package, semi-variogram, exponential models, small-area
