Query: Where geography lives? A projection approach for spatial confounding   Spatial confounding between the spatial random effects and fixed effects
covariates has been recently discovered and showed that it may bring misleading
interpretation to the model results. Solutions to alleviate this problem are
based on decomposing the spatial random effect and fitting a restricted spatial
regression. In this paper, we propose a different approach: a transformation of
the geographic space to ensure that the unobserved spatial random effect added
to the regression is orthogonal to the fixed effects covariates. Our approach,
named SPOCK, has the additional benefit of providing a fast and simple
computational method to estimate the parameters. Furthermore, it does not
constrain the distribution class assumed for the spatial error term. A
simulation study and a real data analysis are presented to better understand
the advantages of the new method in comparison with the existing ones.
