Spatial autocorrelation in deviance residuals for least- and best-fit regression models. Comparison of spatial autocorrelation in the deviance residuals from the ordinary multivariate logistic regression model (upper panel) versus the best-fit multilevel logistic regression model (lower panel). The mark correlation function (Km) may vary between −1 (negative spatial autocorrelation) and +1 (positive spatial autocorrelation), with an expected value of 0 for no spatial autocorrelation. Spatial autocorrelation was substantially reduced, albeit not eliminated, in the best- versus least-fit multivariate logistic regression model.
