Estimated variogram for the mixed-effects model residuals at the municipality level (blue dots) across Colombia, including 95% confidence intervals obtained from a permutation test under the null hypothesis that there is no spatial correlation (blue-shaded area). The blue dots fall outside of the confidence bands up to approximately 120–140 km of separation, indicating spatial correlation up to this distance (confirmed by the geostatistical model)
