Figure 3. Spatial correlograms computed from the climatic debt and residuals of the PLS0 model.
Black and white dots show mean values of the Moran's I index computed on the climatic debt and the model residuals (n=5,000 bootstraps), respectively. Error bars show 95% confidence intervals. The red dotted line depicts the threshold of spatial autocorrelation significance (that is, I=0.05).
